You know, there is such thing as fake snow that won't damage stuff. There is also styrofoam peanuts that could work, too. I don't discount Dave's VCU regional hint. Obvious, yes, but, who knows?
And reguarding the snow, I was out there in short sleaves and shorts. Mostly because I didn't want to carry a coat/long sleave shirt/long pants around. Much easier to be comfortable in the pits and chily outside.
