I live in gaithersburg md, during the spring they come to my neighborhood, approx 2-3 times a week!!! very annoying! i tell them i work for a contractor and do all my own work, which for some reason they dont hear or understand, if thwey come back again they will be told if they come back it will be considered harassment and i will take further actions from there, they are very annoying, irratating, obnoxious, and they all need to get a hearing aid, because i have had to deal with many of their wanna be salesmen, very ticked off.
