Tredyffrin occasionally waits there catching people speeding on howellville road (the connector between Conestoga/Cassatt and Lancaster ave). It’s 25, which is a drop from Cassatt and Conestoga, which are both 35. And it’s downhill, so very difficult to stay under in that direction, and in the other direction you have the Conestoga/Cassatt light that conveniently changes to red as people approach it so to make it you would usually need to go 35 or more. There’s no timing lines to set up the speedtrap, so it’s less likely for them to be at that one.
