Trail-Gator Bicycle Tow Bar

Another bicycle related item...  A Red Trail-Gator which is designed to let you tow a child's bike behind an adult bike.  In the pictures, it actually shows a kid sitting in the bike when you tow it, but I would be a bit leery about using it this way.  My wife used it to tow my daughter's bike to and from school so they could ride together.  I have all the parts, the picture doesn't show everything as a few things are still mounted to my wife's bicycle which I will obviously remove and include.  Trail-Gator website here:
