This past weekend, I visited a friend who lives in Dix Hills, NY. Afterwards, I took action against the sign spammers. I drove along Vanderbilt Parkway, which turned into Motor Parkway. As mentioned in a previous thread, there were signs on every street corner. After an hour's work, though, the signs were gone.
The following day (Sunday), I cleaned up Queens Blvd. in Maspeth. Some idiot put up a bunch of posters on each light pole. My girlfriend and I took great pleasure in taking them down, and putting them in the garbage.
