At our theme camp last year, the prevailing wind was quickly pretty apparent and I wanted to park the vehicles in a line along the upwind perimeter line of our camp. It was along the main thoroughfare, so I let the virgins in my party talk me out of it.
The wind continued to blow most strongly from that quarter, and I daresay that we would have had a more pleasant time if we had erected such a barrier.
The Ranger camp along my street did the same, BTW.
