Funny to see a kind of local Plattsburg bottle posted by a member in CA.!! I'll see if I can do some homework for you on that on as far as who they were as far as brewers and when they went out of business.
There's a lot of wild country around those parts Kastoo[]. I'm sure they'd let you re-up and send you to some other great bottle digging locations, although I dont know how many bottles you'd find in the deserts of Iraq or Afghanistan.. LOL
Or you could always make a vacation road trip and save yourslef the 2-4yr commitment.
Happy hunting!
