Hey Nick,
My name is Ryan. I live outside Jacksonville and have been looking for someone to go on a trip to the springs with towards Gainesville, my top pick being Devil’s Den. I am also a beginner. The springs I find pretty accessible and great for entry-level as opposed to the more ambitious shore dives, where visibility/currents/etc cause concern. Considering your dates of availability, 4/18 might be a better fit. Let me know if you are interested here or direct message.
Vince and ScubaSass, I live locally, so if you are ever seeking an additional buddy, let me know!
