I drag my buddy around on his board sometimes. Usually drunken times. You gotta pay attention to the road texture though, as a few times we went from really nice new smooth asphalt to really old crusty abrasive asphalt at high speeds and he almost lost it! I managed to drag him up the sidewalk on the bathurst hill one time too. Luckily he lives south of st. clair now though.
PS. Wes, I know about that thing, but its freaking intense! Way more work and money than carrying somebody on the back should take
