Our family moved to OR when I was a kid in 1967. Dad worked at Y-12. Graduated from ORHS in 71. My mom still lives there. Nice place. I go back a couple of times a year. It still looks almost exactly the same now as it did in 1967 - except for more restaurants. Back in 67, it was pretty much just Shoney's, Snow White, Woolworth lunch counter, and Davis Bros. Cafeteria. And the only 2 hotels in town were Holiday Inn and Best Western. Ah, nostaglia.
I understand some homeowners in the area had some trouble with the Feds over property rights/title.
About ten years ago a corporate client of mine (yes, I confess to being a lawyer) who was a vendor at the Oak Ridge plant had a dispute. The FBI got involved very quickly and talk of criminal charges were tossed around. Cooler heads prevailed, but I found out that the plat folks did not mess around.
