Hi TSandM,
Langley is the only blow out/alternative site our Anacortes Club uses.
Langley often has very bad Viz. though but is on the opposite side of Whidbey Is.
so is sheltered from winds that effect Keystone. It's also not current intensive.
It's a pretty nice reef dive though and if you've come all the way to Keystone, it's on your way home, at least. the viz. isn't a huge problem because one has one's face right in the reef on that dive anyway.
You've mentioned that you haven't dived Keystone yet so...
A cautionary tale:
I dove Keystone on Sun. It was a minimal tidal exchange day, our LDS' open water cert. dives were being held, etc. while I and others dove independently.
On our 2nd dive, an offshore current turned on like a light switch, surprising everyone. (It felt like almost 2 kts.) I ended up hyperventilating a little-enough to be freaky for a couple of minutes, but going down to the bottom and pull and gliding works fine. About half way in towards shore, the offshore current heads inshore and then you can enjoy the ride.
I actually opted to skip my safety stop for the lst and only time as I was only down a very short time and not deep.
We had to swim around a kelp bed away from the jetty where there were no bottom rocks for hand holds and I felt that it was better to get a visual reference as to how far out the jetty we'd been swept before swimming to it and resting a moment, reconnecting with my buddies and then descending for the pull and glide.
The usual 15' viz was about 6' that day. We ALL got separated quickly and we're all concientious about sticking together.
It really bothered me to not do the safety stop (all problems should be ideally sorted out underwater) but ascended as slowly as I dared. Aside from visiting Japan, it seemed my only option before being swept into the strait while conducting the lost buddy protocol. We descended again and did a safety stop after. After this, I'll try to always stay right along the jetty as the current then only carries you out around to the opposite side (where the ferry docks!)
I've dove here a dozen times as of Sun. and this was the only time that we were all caught by surprise on a minimal exchange so it's generally pretty easy along the jetty. The semi-adjacent pilings are trickier and I've only dove there once with a better navigator than I.
Bob is absolutely correct (he always is) regarding next weekend. Minimal exchanges or at least long slow ones only for Keystone. I'd still love to dive there with you some weekday as 11 out of 12 nice/mellow dives has been the rule! It's really a nice and generally simple dive.
If you ever come all the way up and find you're blown out by the weather, I'll give you a tour of Anacortes if you like. I'll possibly be diving charters in Hood Canal the lst week of June though. Stay in touch if I haven't scared you off now!
The tire reef just south is at Admiralty Beach and is completely open. No jetties, no pilings, no nothing for surface orientation or resting. The only time I was going to dive there, we got blown out and the surf was intimidating. I'd like to try it with someone who's been on the bottom there some time on a nice day.
Hope that wasn't too much and was helpful...
