well pretty much the DNA website didnt have much info but pretty much its a rail jam in the convention center during the Colorado ski and snowboard expo. also its on the notorious DNA "roller" drop ins.
last year at the convention center in denver it was going on during a ski convention and i asked the guy how to get in this and he said if i had my stuff i could hit it. (i didnt have my stuff) but if its not a comp i would just go maybe a bit early and ask if you could hit it for fun cuz the guy said i could no problem just bring your stuff
