skidhopping can only be done when theres alot of snow on the ground, and its cold enough for the snow to stay packed on the roads.
skidhopping is not for the fainthearted, I havent done it since I was a teenager.
I have only done it in the northeast part of the US, tho I imagine the climate is right for it in other areas.
skidhopping is this:
when theres a good inch or more snow on the roads, and people are still driving (like they do in areas where snow is common) the idea is to hitch a covert ride on someones bumper, when they come to stop sign or intersection, and see how long you can hang on, lol before the driver either accelerates too fast or catches on the scam... me and a friend once skidhopped a churchvan for like 6 miles to get home one winter, back in like 94 or so... its like barefoot water sking, except wear some old boots or shoes, they will get trashed from the friction after a few hours.
