Nope, never have had a problem with that. As long as I have rocks on the bottom and poles leaned against.

Lots of remote trailheads in the canadian rockies have stashes of chicken wire handy for just this purpose.

The other thing that works well, and tangles less, but takes more room is an appropriately sized 3 foot tall roll of vynil clad chainlink fence. I got a buddy who carries one in his pickup for this purpose. YMMV.
