Just went to Blue Grotto $40.00 1/2 day pricey I like to change it up with variety. How about Manatee springs $6.00 in Chiefland Florida not far from Rainbow? Might consider Rainbow in the Am if it is OK with your isrtuctor? Who is your instructor does he teach cave, helitrox and or deco maybe I could talk to him about future training? We’re you diving Sunday allso?
