MJ - thanks for your response. I am having a hard time picturing the design of your support structure. Do you have the 2x4 resting on the windshield?? Extreme James did that last winter and busted the windshield on his steigercraft. Maybe you could post a pic when you take the tarp off, this spring.
I like the slick spray idea. :) I have a steep tarp the way it is, but a heavy wet snow still accumulates. >:(

I think the worst of this winter is behind us - it hit freezing this weekend. :D
