LOL!
Is that two inner tubes? Does it actually work up logging roads?
looks like that's what they're using (i stole that picture from the interweb)
but yeah. we use a similar setup (cut innertube tied to my seat rails, wrapped around the little guy's stem and secured with a carabiner) for three years and it works a treat. i've towed him up fromme many times, mt. jofferey, sumas, up the mamquam to hit half nelson, a few fire roads in whistler, etc. i wouldn't use it on singletrack but we've never had a problem on fire/logging roads
i'm starting to see more people using this system, especially on fromme. i complimented one guy on his setup and he actually stopped and thanked me, said he'd seen me towing my son up fromme a year before and started doing it himself, loved everything about it
