I was at the coliseum this past weekend for my son's hockey game. They were clearing the snow off of the roof so had to snap a picture because I thought it was crazy how much snow had come off. Everything that's piled up on the ground alongside the building was already been shoveled off.
glad they look to be tied off as that has to be a slippery situation. Also interesting that it looks like they have a sheet of plastic (under the lift area) assuming to help the snow slide off (assuming they move this plastic when they move to the next area to work on).
