I have a lightheartgear solo non-free-standing tent which I recently took the the Sierras. I generally like the tent, but found on several occasions that I had difficulty setting it up because I could not get my (very lightweight Ti shepard hook) stakes in the ground. Yeah, I guess I could get beefier stakes, but I'd like to avoid that. In any case, there were areas where, I think, even a stronger stake would not help.
REI makes Snow and Sand Tent Anchors, but these are not lightweight.
I'd appreciate hearing from people who have found good (ultralight) ways of dealing with this problem.
