I have a townhouse on Crystal Lake that is for rent. 3bed/2.5ba with dock on a freshwater private lake not even 5 minutes from Rixen. Email me at firstname.lastname@example.org if you are interested and I can talk to you more about it.
Crystal lake is a good spot to ride and I don't think there is public access. It's been a while but I used to run the course there when Jim ran the school and we were always the only boat on the lake. At one point they were going to add lights.
I think Dean Lavell is now running a school on the lake. Check out his website. It's also a stones throw from Ski Rixen.
Full of snakes. Everybody who goes there gets bit. Three alligator attacks in August alone. Now the exotic pythons have been snacking on full size dogs from the shoreline. Too close to the everglades I guess.
