Ginnie Ballroom, Blue Grotto, Paradise Springs (I am sure there are others), are all overhead environments that are "open" to OW divers.
We are told to NEVER go into an overhead, no matter how benign, until you have the training and certification. People on SB actually debate whether it is safe to go through coral arches as they are technically "overhead," but the above mentioned sites, which are certainly caverns with cave extensions, are open to OW divers by their owners.
Hey, "don't go into any overhead, watch "A Deceptively Easy Way to Die", give me 30 or 40 bucks, sign the waiver, don't take a light (unless you sneak one in - I won't watch), follow the thick heavy line, and try not to kill yourself."
No wonder many think that training limitations are a joke!
