There are \u00a0a lot of businesses in Wilton, thanks to a thriving town center and commercial development along Route 7, but you would technically be hard-pressed to find door-to-door salesmen. This town of 18,000 residents has a grand total of only four vendor permits outstanding, and those are for two ice cream trucks, from College Creamery and Gigi\u2019s Family Ice Cream, a financial advisor with Edward Jones Financials and the Wilton Housecleaning Service, according to records available from the police department.. Other than that, magazine salesmen, lawncare pitch artists and solar panel canvassers are all off-limits in town. If they show up at someone\u2019s door, they do so at their own risk because the town is very particular about issuing vendor permits. \u201cThey should be readily identified by their ID card around their town lanyard,\u201d said Lt. Stephen Brennan, spokesman for the department. \u201cIf it is not on their outermost garment, we will ask for it and make sure they are in compliance. If they are not, we may cite them with an infraction per the town ordinance.\u201d There are occasionally complaints from the public about door-to-door salesmen, but the incidents are fewer in number than they used to be, Brennan said.
