that only seem to come out at night? Last night I was coming home from work; it was well after dark, but the streets were fairly busy, when a gaggle of motorcyclists came whizzing by. There were at least 20 of them, all riding similar Japanese bikes, what we used to call cafe racers, definitely not Harleys. They were breaking every traffic law possible, zigging in and out, cutting people off, tail-gating, you name it. Having a great old time. Is this a popular night time activity that I'm just now discovering?
