On last Fall's tour,I was coming from the north into the town of Santa Maria, California.. A really weird thing I saw was an older man on a Cruiser type bike had built a little platform atop his rack on the back of his bike.
He had a medium sized dog riding with him within the platform that had sides on it like a milk crate. That was pretty strange, I thought. Older guy probably not ride too fast. I would hope the dog would jump off the bike safely, if he needed to. The dog looked pretty content..
