Steve was invited by Sue so we didn't know anything about him except that he's pres of the location mtb club, RATS - Rockville Alternative Transportation Society. Turns out he rode a single speed over EVERYTHING! Just the fact that he was riding a singlespeed should have been our clue that we should have set our own route. I think he really wanted to show us his local gem. I told Sue that if he shows up for the next ride he has to stay in back or take a separate group that wants to do black diamond stuff.
