I didn't realize the glass made up 75% of the weight.I'll keep the front glass in. I'm thinking of keeping the whole rear panel and tilting it forward until it meets the new roof line. But then I'd only have about 5' of 10ish° slope and then a steep drop maybe 45-70° I could figure out the exact angle but I'd need measurements.
Last night there was still some residual snow on the side of the driveway. There's still ice in the creek and plenty snow in the woods yet.
