Nope. Your suggestions about the ground tarp, coupled with the fact that we used only vented heat with our new stoves, was dead on!!
Worked great! Thanks.

We are heavy and takes time to set up, but we have a drive up camp and a little work is part of the fun!!!
The day we got snow we did have some sweating.....but we were cooking and the temp went from 50 to 30 in a hurry!!!
