On River Road in Niskayuna there is an old train station which has been converted into a park by the bike path. A little bit down the road from there heading west is a one lane bridge which leads over to an island in the river. Between those two points, more on the bridge’s side, there is a large cutoff where a cop will sit facing west, but watching/tagging in both directions.

Other spots a cop will sit are in the Park’s driveway or down a small hill near the described location.

The road is a 35mph zone but you could easily go 50 without realizing it. They will.
