Someone on another forum posted this CafePress link:
This link won't work (it contains an expletive that was replaced with asterisks here), but I think you can easily figure out the correct spelling.
It is advertising t-shirts, etc. that say "I don't share the road" and shows a car hitting a bicycle. Just what we need...
People on the other forum have been sending emails to CafePress; might be a good idea so they know that there are a lot of us who don't find this funny!
