As for myself though, I just went out and drove around looking for
dark country roads. A low area is actually kind of good, because
seeing
is usually rotten at the horizon anyway, and surrounding hills can
block
out distant lights.

That's what I did and it only took an hour or so of driving around
(once I got in the area) to find a suitable site. I've been using that
site now for four years. It turned out to be private property, but
most land is. If its unfenced and undeveloped, chances are that the
owner won't mind you using it. In my case the owner and his kids just
happened to be there one night but once he saw that I was harmless he
said I could use it anytime for this purpose. I've only seen the owner
that one time in a couple dozen visits.

Cheers,
