I've run into creepy white-bearded bike guy on the Burke Gilman Trail, so he obviously uses the whole of Sammamish and Burke.
His MO seems to be hanging on a woman's wheel until she stops her bike. Then he tries to chat or just hangs around until she starts riding again. (I could NOT get rid of him until I caught up with my group and made them all stop so he went by.)
He is creepy.
Next time I see him I'll yell at him not to draft and to go around.
