I have a private club range that's about two miles from me, but its only open to the public for 6 days a year. And I don't have the money to join.
There is also a privately sponsored public range in the next town (about 17 miles) west of me.
That is a decent range, limited to 200yrds., fully covered benches in a "house" concrete cylinders to shoot through.
Otherwise, I too have thousands of acres of National Forest to shoot in. With many small "gravel pits", the problem here is also the trash left behind by others.
