So this summer I'm thinking of building a jump and a rail in my backyard. I'm wondering if you guys know any companies that sell synthetic snow that I can use in the summer. The only ones I've found are mSnow.
Sorry, I can't help answer your actual question, but I did just build the rail design in the build-a-jib 101 site this afternoon. I had the 4x4 and the screws - everything else cost less than $50. I used a 2x6 and three pieces of PVC on top to make a wider rail. Hopefully I can get it out to my yard this week!
