I live in the Tetons and finally fixed my hammock stand so I can really start testing my winter abilities/setup. What is the best way to secure my tarp in the snow? Planning my first real winter overnighter later in january for my birthday (probably gonna ski in about 5 miles to a hot spring). I've been good down into the high teens, but the ground wasn't balls deep with snow. Also, I have the wbsf tarp, 20 degree bag, 0 degree hg incubator, no vapor barriers or uq protecter, should I be concerned about moisture, been reading alot of stories about wet gear!!! Thanks to you all for the community we have here!!!
