THAT'S FUNNY!!!
We did that as kids using rope! Stopped being funny when we crashed!
Also Dad used to tie rope on the back of his pich-up truck and tow several of us around at campgrounds.
He was hard of hearing so when I fell off the bike one time, I had to watch in horror as Dad happily kept driving, unaware that we were yelling at him to STOP. The rope had snagged the handle bars and he dragged my bike about 200 yards befroe he realized I wasn't ON IT anymore.
Hope the eBay sellers LIABILITY INSURANCE is paid up!
