The first time I saw the "sack" hanging from the hitch of a pickup truck a couple of years back I had to do a double take, then I noticed the bumper sticker that said "Yes, those are Testicles" and laughed out loud in my car.
I usually try to ride CR around 7:00 on Saturdays, so hopefully I'll be able to meet up with some of you this weekend. I'm assuming you will be meeting at the Newmans Lane lot.
I can't watch that here at work, but my wife made one for our family too. We don't have any kids though, so our dogs had to do.

Thanks for the tips, head on encounters aren't a problem, it's just coming up from behind that seems tougher without spooking anyone or "stalking" them. I'll give the mild cough a try and maybe put a bell on, but I usually reserve that for rail trail type riding when you encounter many more people.
