I chose not to post a vote, as I find the wind conditions you correlate to terrain seem to not apply to the mountains. Most of my hikes are in the Whites. My perfect campsite is a place unviewable from the trail, adjacent to a flowing stream or waterfall, and has a fallen tree or boulder to sit on. Perfectly spaced trees, of course. I don't pick anywhere near the tops of mountains (too windy).
