Snow bongs? Is that like when instead of putting ice in a bong, you put snow in there? As someone who has spent his whole life in the midwest, I can attest to doing this many times.
That's exactly what I was going to say. Besides... snow can be nasty coming down. Especially in densely urban areas. If you live in the middle of... let's say... Pasadena, TX. DON'T DO IT! Trust me.
