Or sponging the tunnel going into Downtown portland...anyone ever do shit like this? The freeway overpasses must be easy to do it'd be pretty funny to do at like 4am and see how long it takes them to take it down.
I remember someone in LA put up better directions about getting off an exit super covert. He had like full on proper outfit to the local road workers so he would blend in.
I want to put something L*kers related early in the AM, secured with chains so they just can't cut it down.
