Is it generally okay to cat 6 the bike cops? They are always going like 10mph and I'm generally closer to 30 but I for some reason am worried that they are going to look at me from behind and see I don't have a rear brake and ask me to stop. Plus, even though there aren't any signs posted I'm pretty sure the speed limit on the trail is 15mph. I guess I could always pretend I didn't hear them but then I'm afraid they'll radio ahead to someone. Am I being paranoid?
