The pictures of the guatemala sinkhole are almost unbelieveable aren't they? If I occupied any propery around there, I believe I would be exiting rapidly!
The sinkhole problems seem to have been around for years in Florida and Lake Okeechobee. When I Googled that reference, I saw many links dating back to 1997 and beyond. I didn't see any describing airboats & passengers disappearing? Do you have a link to that story?
