I built a skicross start gate with a buddy, but no longer have a home for it.
It would make a great drop in for a summer setup, or maybe a drop in although it is a little heavy.
It can be used with the gate down, and you can get a ton of speed by pulling off the handles.
It's in a few pieces, but can be reassembled pretty easily.
I live in boulder, let me know I you have any questions.
