I use tarps for my rail. They are decent. It's pretty darn slow. You HAVE TO use water and dish soap. You continually have to reapply the water and dishsoap so it stays fast. Build a really high and steep in run, because the small hill in my backyard doesn't give me enogh speed to have a jump up to my rail. (I made a trapazoid rail because of this).
Imagine the ns outcry if u(lateralis) were banned. There would be countless threads and petitions to bring u back, it would be like when treadway got banned from whistler. Someone would probably make and sell 'Free Lateralis' stickers and shit. -j
