BMX - plastic jumps?

does anyone know where you buy those little plastic jumps i have seen kicking around the neighborhood on occasions?

Walmart probably.

wait, i might have found my answer. i think walmart has the little plastic ramps. has anyone bought them? i actually wanted to buy some and "cap" off some dirt jumps i made in the woods for mtb "free riding".

i'll obviously make sure it is safe. these little plastic jumps look like they might make for a nice jumps in combination with some dirt underneath. has anyone done this? i just have no help building the jumps and using dirt can be tedious and make you feel like you are getting nowhere. i thought this might save a little dirt on the upper part of jump.

thanks

Probably wal-mart. I don't know why you'd want one though, they're ******** as ****.

edit - Too slow.. I don't think they'd work too well as part of a dirt jump, part of the good thing about dirt jumps is you can change the angle and everything, and tires hook up on dirt a whole lot better than plastic, so transfers might be easier.

Plywood and cinder blocks.

refrigerator, and other large object... I don't remember who did it, but someone on here did the refrigerator thing.

yeah ok, thanks for suggestions guys. i was just looking for an easy way out. :D

i am not use to this hand shoveling :( . i am used to bulldozers and bobcats for mx :)

Those plastic jumps are horrible.

Plywood and cinder blocks.
Old school.

All the way.

Those plastic ramps suck, my littles sisters freinds have one, and they ride there 16" off it, they are 7.

Haha.
