problem 1:so i have a super small backyard (12 by 12 foot concrete) so i would have to set it up in my alley way i have a bunch of tarps that i could put everywhere but would that help? has anyone ever set up something over concreet?
problem 2: i need a dropin but i have a two foot skate board ramp i know its short but would i get enough speed with pvc rollers? this ramp is on weals so i can get t to the local ice rink if i must or should i just build a new one?
thanks for any help
