I took a trip to Florida to go diving.  I did three tanks in the caves in Ginnie Springs.  It was a great dive.  The cave is about 45 deep and 120 feet horizontel.  

Cost to dive $30 per day.  $5 tank refills.  Water temp was 72 degrees.    I don't have any photos that are good but, the guy I dove the cave with sent me a couple.  I will upload on this group.
