You need to get a leash so he can go outside just a little ways... of course then he'd probabl try to jump and end up dangling in midair.
If he had a harness, it wouldn't hurt if he did that. Just surprise him greatly. ;-)
I forget...are there any areas along College where they don't have sidewalks? I'm thinking of walking to The Catholic Store (they really coulda picked a more original name...), just to get out, but I'm afraid of getting halfway there and finding out there's no easy way to walk.
