Sad that you have to pay for it here.
When I was an teenager in Arizona, we would just go out into the desert north of Phoenix and shoot great distances for free. And camp. And make large bonfires. And drink beer.
We had the WHOLE desert to ourselves.
I sure do wish we had open spaces like that to camp and shoot. However $75 ($50 for members) is still pretty good considering where we are located. Also they only have 4-6 frontier Sunday events per year so thats really only maybe 120-160 people who can shoot there all year.
