(My answer, reprinted)
I'd look for all the brown spots during the afternoon. Then I'd set a gun up at each one. Then at night as soon as the temp went below 28 degrees I'd start blasting two guns on each spot, and I'd blast all night long, huge piles that I could spread out. Maybe I'd even get tempature sensitive switches that would start the blasting automatically. I'd ride around on a snowmobile all night long to make sure everything was going good. Then at first light, I'd rip some tracks before the mountain was open. Then I would go home an make oatmeal and go to bed.
