So it's not Salem, but you might find dorkbotpdx to be useful (http://http://dorkbotpdx.org/
A bit of a drive but full of bi-weekly goodness.
Too bad Salem is a geek ghost town.
EDIT: Oops, I didn't read your first post close enough. I see you probably know about them.
So... maybe it's time to start something like dorkbotsalem? When you boil things down, dorkbotpdx is basically a group of guys getting together for beers, showing off their latest projects and talking all things geek for a couple of hours.
Just a thought, but if you could find a place that had beer and wifi (basic staples), maybe you could start having meetings someplace (try keeping dorkbot meeting nights free and you might find a few people willing to carpool). Start off with a couple of guys bringing their current stuff... even if it's just a Uno and a breadboard... advertise on Craigslist or something... You wouldn't have to be an expert - just interested in making things. Show your passion and everything else will follow.
Maybe that'd work? (if you build it they will come...)
