I was browsing your cave site and came along an intresting page you had up on 'Mystery Sink' located in winterpark. I grew up in Biltmoore Shores, which is the development that is right where the sink is located. I remember climbing the fence as a kid simply to go look at the sink. I was always intrigued by it and it's size. Since I was young, it was huge. In order to assist your listing of it, I thought that a more detailed location would be good. 'Mystery Sink' is actually close the the corner of Fairbanks and Coronado Rd. The whole property is completely fenced in by a 6' tall fence. I will admit that because of the trees and brush, as a kid, it made great cover from the owners to gain access. My friends and I never went down to the water, cause it was a heck of a drop on our side (about 50ft). We loved to go there and look at it though simply because of it's great stories. I only saw the old woman that owns it once, and let's say that I don't think she appriciated us kids being there. :-) Seeing your site with some of the stats on it's depths, just make it that much more intriguing. Maybe one day we will have the technology to make it accessible to all true extreme divers, until then, I guess you'll just need about $500K in equipment to dive that hole.
