Just before you cross the Green Island Bridge going towards Troy, there is a small access road on the right hidden by trees, that leads to old refinery fuel storage tanks. The cops sit there waiting on speeders & other nonmoving violators (covered license plates & tinted windows especially). Coming from Troy you have a slight advantage, it is possible to see them if they dont park too far back or hug the tree line on either side. They are armed with light meters as well. If a cop tries to pull you over, continue over the bridge into Troy and take a right into the restaurant parking lot on the corner to stop. The bridge is very small, should only take a few seconds to cross. The bridge takes you from Albany county into Rensselaer county. If you want to fight the ticket, you can use jurisdiction as a defense. Dont stop on the bridge unless you have at least crossed the midway point! Green Island is a super tiny village and the court prosecutor should be no match for a well prepared defense.
