Cool Blogger: XXX PROPOSAL rolled us inverted and stopped the roll. I let her hang upside down for a minute then rolled back level. We leveled out at 25000 feet and I pointed out Orlando and Tampa. Later when I could see Lake Okeechobee I asked for a decent to ten thousand feet. The center cleared me down and switched me to a different frequency. When I had contact I canceled my instrument flight plan and proceeded on visual flight rules. I continued my decent until we were skimming just above the saw grass. I had reduced power and we were only doing about 225 knots. We saw some air boats and I buzzed one. We saw an Indian village in a thick cypress hammock, or island. We crossed the Tamiami Trail were over the mangrove salt water swamps shortly after that. It wasn't too long before we were over the open water of the Gulf of Mexico. We had over 75 miles of open water to cross so I climbed back to 8500 feet. Twenty minutes later I called Key West tower and was identified on their radar. They gave us a vector around slower traffic and cleared us to land. I followed their directions to the FBO and our tie down spot. We parked and I shut the jets down.
