I live very close as well. I moved here about 9 years ago,..and still find it difficult to search out new spots to shoot. If you travel about an hour west you can get into some decent crown land.
There's a few clubs/ranges out west that might work for you. Not sure if they're still taking memberships or not but might be worth checking out.
