Yes, we do have an official "mountain" in Florida. Located northwest of Orlando, it's called Sugarloaf Mountain and it's the highest point of elevation on the Florida Peninsula at 312 feet!
It's a nice area and a nice ride. Weather was great. The ride through Sugarloaf isn't that long, but when you tack on my ride up and back it was a 200 mile day. There it is.
The ride also gave me a good 5+ hours in my new Seat Concepts Saddle.
