Coming down a long hill on Michigan Ave, two blocks North of Hwy 192, officers stand with hand held radar on the side street. They stand far enough to the side to blend in with the trees and shrubs and pop out into the street to wave over cars onto the side street to be ticketed. They could have cars or motorcycles and be there at any time during daylight hours. Michigan is only a couple miles long and this is one of three regular traps I know of in that few miles.
