yeah I guess ppl put up signs for all kinds of stuff... I once saw in norway a sign warning about a sign commin up futher up the road... like "warning 300 meters to sign"
If you look closely at the bottom it says: Also The Bridge Is Out Ahead.
I guess this would be logical in the USA.
Some idiot might cut himself and sue the government.
lol this is just a sure "sign" that the worlds gone mad
