After so many excuse me, excuse me, excuse me on the bike path.. then I yell HELLO! Is any body home? Sometimes "hello" grabs their attention. When that doesn't work, I used my ever so loud police whistle. I blow it continuously as if my butt was on fire. Even after all of that, sometimes he/she wants to be a d--k about it as if to say, I’m not moving and I dare ya to "hit me" Well, I’m up for a challenge any day. The final straw…as I'm moving towards them still a good distance away, I say out loud....are you going to MOVE or do you want me to do it for you? Within sec’s, I guess they imagine their a$$ flying through the air. HA HA
