I live in Portland but I make it out to Sandy fairly frequently, and I'm looking for somewhere I can post up on my weekends, do a little camping, and hopefully decrease the local dog population. Any area-specific tips are greatly appreciated. I also frequent the coast (Newport to Astoria) for vacationing and areas in the Tillamook State Forest for target shooting. If anyone knows a decent less-traveled spot out that way I'd be equally grateful. Thank you!
