This weekend in stoke: Walk on (artificially frozen) water at Early Bird Snowboard Rail Jam

If you're the praying-for-snow type, the Saint Francis Center Episcopal Diocese of Denver is ready to make you a believer on Saturday, presenting the Early Bird Rail Jam "first snow shred of the year" at the Believer's Center of Denver (180 S. Garrison Street in Lakewood) on the campus of Colorado Christian University, in partnership with Denver's TS Boardshop. Get there at 2 p.m. for a sample sale with product from Vans, me.glad,, Quiksilver, Saucer Wax, TS Board Shop and more, and to witness the miracle of artificial snow in the making. Registration starts at 4 p.m. and the jam will go well into the night. You'll probably be subjected to some proselytizing in the bargain, but what the heck: Might as well get your prayers for snow sent up early. God loves snowboarders.

And if that doesn't stoke you enough, there's more...

And, for a proper battle of the sexes, get to the 1stBank Center right at 7 p.m. for a demonstration bout between the Denver Roller Dolls' Green Barrettes and the new men's roller derby team the Rollin' Bones of Colorado. "We scrimmaged against them this week, and let's just say it's going to be a fun one to see," says smirking Green Barrettes' jammer Julie "Angela Death" Adams. "It's going to be brutal."
