Late at night, particularly on the weekends (Friday – Sunday evenings from approx. 10/11pm onwards) cops like to hang out in front of the Electronic Express on West End Ave. (2 buildings up from Centennial Park).
Typically there are a minimum of 2/3 cops sitting, with radar guns, on the curb checking everyone coming down from the bars just past the Vandy area but I have frequently seen anywhere between 5 and 8 (yes, 8) cop cars sitting out there at any given time. Not only are they checking speeding but they frequently pull people over to do "random" license checks as well.
