All,
Pedro from Northern VA (Bristow 10 mins from Millbrook Quarry). I started out diving in Aug 2004 and practically lived in the quarry until I joined up with the Magothy River Association (MRA) in May 2005. I exclusively dive at the Magothy River (near Arnold, MD; north of Annapolis) doing volunteer oyster reef conservation projects. When I visit my family in Orlando, I usually dive in Jupiter and New Smyrna, although I have also dived in Key Largo, Clearwater, and Crystal River area.
As far as group outings are concerned, Lake Rawlings and Dutch Springs would be good choices. VA Beach would be the best daytrip wreck dive location. I have gone to VA Beach twice and still haven't had a good dive, I figured I give it one more chance.
