There's a big yard outside Russellville full of cool stuff. The owner usually drags a couple up to the Petit Jean swap meet each year, but I hear he's in bad health. I've got a buddy that's bought several old Caddies from him in the past few months. Not sure about prices, and I do know that he crushed several hundred cars a few years ago when he moved to his new location, but it's worth walking through.
The hills are full of stuff. I'm always surprised by what I find ambling around. A drove through that place in Maumelle once a couple of years ago. Did not see anyone. Several older but nicely kept trailer homes inside. Spooky. I didn't get out of the car.
