Connecticut State Police on Tuesday attributed relatively low numbers in holiday enforcement to the gloomy weather keeping people from their original weekend plans. Troopers began Memorial Day weekend enforcement at midnight Friday. It continued through 11:59 p.m. Monday. \u201cThe cool, rainy weather throughout the weekend likely affected these statistics as beach, cookout and party plans may have been canceled,\u201d state police said.
