OK, here's an idea:
If you blow snow on your roof, and build a small lip so you can clear the rain gutter, you will need a few bales of hay to make a nice landing hill plus still have room to stop before you go into the street.
I didn't say it was a good idea, but it sounds like fun.
And though it's been done before (in a cornfield, I think), maybe the people at Warren Miller will be interested . . .
