Sorry to give you bad news. They have signs at each ramp. I'm not the self appointed police, I just try to follow rules. IF everyone went 10mph, that would be just fine. But you know that not everyone will do that. They will just keep pushing it up a little more each time. It is funny to watch people bring their boats to launch and as soon as they see the park police, they leave pretty fast. I operated for 1 1/2 years with just a trolling motor but I'm sure my boat is smaller than yours. Come on and join the fun. It is nice to go out there on the weekends and not get run over. But you do have to watch out for sailboats.
