So what do you haul on your bike? Books? Your laptop? Maybe a child if you have a baby seat? Well, I stole this off John Speare's 'Cycling Spokane' blog as a sample of something different you can haul- pets! Well, people with normal pets anyway. If I tried this with my cat Bob, he'd chew his way out of that plastic carrier, kill me, then drag the bike off to a pawn shop sell in order to buy some catnip from Canada.
