Oh, man, this reminds me of when the default username/passcode was being shared for the displays. 4chan had its moments. I wonder if they are still the same...
Yeah - I remember reading about how these signs were laughably easy to "hack" a few years ago.
I thought about it for minute when the city installed one down the street. Then I imagined the weird shame I'd feel when my neighbors inevitably caught me, so never tried it out. Actually, in retrospect, they'd probably have helped.
I always wanted to warn about radioactive bears ahead. I don't know why that was always the thing, but it seemed silly enough to make people smile while scaring the idiots.
That's so charming! It's my absolute favorite thing today.
Where I grew up there was an urban legend about radioactive deer. It was pre-internet, the deer were legitimately weird, and they lived in the woods adjacent to one of the US's earliest nuclear research facilities. Everyone had seen them. The facility was active and well guarded. It seemed... plausible. Very plausible.
