The weirdest thing I've seen on a ride was a guy towing a full size fiberglass rhinoceros on the bike path north of Ventura, CA. He was towing this critter southbound down the whole west coast to raise awareness to protect the rhinos. Funny thing is that a friend in Seattle saw the same guy on a bike path up there, a few weeks earlier and sent me a picture. I made a donation, and posed for a picture.
