Miss Almira Gulch in the Wizard of Oz had a pretty nice rig!
- My bicycle has been collecting dust for too long. Maybe what I need to do is add a decent terrier box off of the back. Of course, if you have money or can weld, you can carry a lot more than a terrier on a bike -- I think a Great Dane is well within the bounds of possible! Check out these extended- frame bicycles. For those with terriers, the options are simpler, from jury-rigged plastic milk crates to fancier rigs like this, or this, or a well-mounted wicker basket like that in the Wizard of Oz.
- For those who motorcycle, check out these options, from dogs to cats, and from monkey to sheep. Back when rocks were soft (and so was my head), I occasionally commuted to work at a Maryland boat yard (we built big cruising sailboats) with another fellow and his massive Labrador-cross named Kilgore. Rich would drive, I would sit behind Rich, and Kilgore would lay cross-wise between us, with his front paws on the right and his back paws on the left. We never had a problem.
