When I had some free Bachelor time a few years ago because my Wife was out-of-Town, I did Recon on where to Boondock for a week or so in my lil TT. I looked around Arcata CA on line, just north of Eureka. Various Blogs and commentary fleshed out a scene I was not willing to deal with. Lots of Transients, and RV break-ins/theft. I also was not willing to withstand the constant Panhandling; a real problem that City Founders are trying to combat. I just like to wander around and be left alone, actually.
I used to Hitchhike in my foolish youth, and I'm still an adventuresome guy. I did LOTS of Int'l Biz Travel into dicey Urban areas. But, my conclusion about Arcata was 'thanks, but no thanks'. Too much 'work' in trying to enjoy some time around the area. Arcata got the reputation as being a 'refuge' that Transients could go to and get by. That rep and scene feeds on itself, and folks just keep on heading to there. I know 1st Person that Boulder CO is a similar destination. However, the Transient issues are as severe as what Arcata sounds like.
There were some neat Festivals pictured in Arcata Blogs, and I'm sure there's lots of positives. The trick might be to hole up in a nice, well-watched Campground and take Bikes or the Toad into Town with NO valuables to be snatched; even in the Trunk.
