I would love to have a dry run through the winter. I am just a young girl who isnt capable of adding a roof of some sort so the best I can think of is to add a tarp to it. How much snow can a tarp handle? I live in MN so we get a decent amount. The run is 10x10 and is covered with chicken wire. No other wood, just chicken wire run across the whole thing, kinda loosely. Would it be strong enough to hold a good foot or so of snow? Thank you!
