Scubagal4579:
I'm in the Silver Spring MD /DC area. I usually "export" for my diving, I like the Carribbean because of the closeness and temps. I usually make two or three trips a year (but would obviously prefer more). I am open to learning about dive trips around the area but would rather not have to don a drysuit to get wet.
From the Silver Spring/DC area there is a lot of excellent diving, however, only some of it can truly be said to be warm water diving. For salt water there are four basic areas that are reasonable driving distance for weekends; (N to S) Ocean City, MD; Virginia Beach, VA; Hatteras and the Outer Banks, NC; and Morehead City/Beaufort, NC. The gulf stream comes up the coast as far as Hatteras, then it is directed out into the Atlantic. This means you have clear, warm, high vis water with turtles, rays, sharks, large pelagics, etc. in Morehead City/Beaufort, and on a good day the offshore wrecks offer world-class diving. It involves charter boat fees and hotel rooms, as well as travel costs, but makes for awesome weekend diving - so long as the weather cooperates. Summer temps can run between 72 to 78 degrees (F). From Morehead City north each location is progressively colder: Hatteras summer temps are mid 60s to low 70s; Virginia Beach drops to mid 50s to high 60s; Ocean City, MD is often the same - but on the deeper wrecks it can get into the low 40s. As with most things, it's a trade-off. Morehead City is a 7.5 - 8 hour drive from Downtown DC so long as the traffic cooperates. (Traffic during summer weekends can be nightmarish...both getting out of the city on Fridays and back into the metropolis on Sunday nights...) On the other hand, you enjoy world-class diving, assuming you don't get blown out. Ocean City, MD is about 3 hours from downtown DC if traffic is light. Plus, you can live on the boat, so no hotel fees. The downside is that the water is much darker and colder. Still, we've decompressed while a pod of dolphins frolicked around us off Ocean City, and there are some very cool wrecks there. [All along the eastern seaboard the wrecks with most history are WW II wrecks torpedoed by the U-boats - of which there are also more than a few out there. You're looking at long boat rides, 2.5 -3 hours out (one way), you're 60-70 miles offshore, but the diving can be bodaceous.]
Freshwater there are four options also, Lake Rawlings (3.5 hours south); Millbrook Quarry (about 1 hour due west from DC, perhaps 1 hour 20 minutes from you); Mt. Storm (about 3 hours west from you); and Dutch Springs (quarry) in PA. Of these, I go to Millbrook and Rawlings exclusively; Rawlings because a camping weekend there with a roaring fire is highly cathartic, and Millbrook simply because you can get out there for a dive at 8 AM on Saturday morning, and be home by 1 PM to do other stuff for the rest of the afternoon. The vis was suck-city last season, not helped by the legions of classes that go there for open water check-out dives, but the convenience simply makes it the logical choice for practicing and skills dives. You may find that some of the others work better for you, but these will be your primary options.
In fact, if a group of divers is getting together to do some diving over a weekend, you'll likely find that they're heading for one of these eight destinations. (Of course, there are a number of different charter boats at each of the ocean destinations, but this gives you a general idea to start planning for next season...) If you're willing to don the drysuit at all, Chilly Willy dives at Millbrook are a cheap and easy way to maintain skills over the winter. The December dive is next Sunday, Dec 17th; and the January dive is Sunday, Jan 14th. I won't be at this months, but if I'm around I may hit Millbrook in January. It will be weather dependent......

but if the sun is out and they put together a big fire it can be reasonably laid back. The Chilly Willy dives are run by The Dive Shop out of Fairfax, VA.
The fresh water dive sites offer generally suck diving - although they are excellent for teaching, training, and practice. And that's the point: a charter boat 70 miles offshore is a really bad place to discover that your mask leaks, your regulator is breathing wet, you don't really know how to use your compass to navigate, or its been long enough that you're apprehensive about dropping into a hundred twenty feet of open ocean. The open ocean is the shizzle - thats where you want to be. But the weekends spent in the quarries ensure that you're ready for it; they are absolutely necessary for you to be comfortable and relaxed in the ocean.
It's all good. And 2007 is going to be a most excellent season!
Hope this gives you the general lay of the land around here. Welcome to the area.
