snow snow snow and boys

I have icicles hanging off the roof, the deck, the truck, heck even me, it is bitterly cold, that dry cold that makes your lungs hurt to breathe.....what we got today was all powder...pure perfect powder flakes that keep coming even now but not as large and heavy, we live in the mountains in a neighborhood where most of the homes sit empty as 2nd or vacation homes for bay area residents, some homes are vacation rentals and I think in this housing glut some are being rented yearround to the young 20ish kids that snowboard and seem to be mostly guys, well the house beyond a vacant wooded lot from us just rented last week to 4 of them, i think the home is maybe 1000 square foot, so yesterday when the snow began to fall they put a ramp, my husband said a half pipe and let the snow cover it and then today they spent the better part of the day, 5-6 hours, shoveling snow into a full on half pipe, now they have a subaru with a tow rope and a snowboard connected guy that gets towed up the street then back down at about 40 mph then the snowboarder lets go and goes up the ramp and back down, but to me it looks like they are trying to get air.......they groom the slope and have industrial lights out to light it, just wild! my fear is I have a son, how long until I am worried about him and his hijinks?
