don't give up on the bike paths tho - they are a wonderful way to ride, usually very peacefully! if it's any consolation - you probably scared the bejesus outta those boys, might make them think twice next time! I'm sorry to hear about your "close encounter" and I'm glad it didn't end up being something more serious!
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, champagne in one hand, strawberries in the other, body thoroughly used up, totally worn out and screaming: "Yeah Baby! What a Ride!"
