A four-way race for two spots on the Board of Selectmen appears to be shaping up, with more than a month remaining for candidates to file nomination papers. Board president Jess Aptowitz is seeking his third three-year term and said in an interview he “is ready for the challenge.” Incumbent Kevin Moran, meanwhile, said in an interview he decided the time was right for him to step down. But Moran said he will miss working with the board and Town Manager William R. Ross, whom he called “one of the greatest people” he has ever worked with. Moran said he will spend more time with his teenage sons and in his job as an inventory control manager for a growing company. Town Clerk Marianne E. Staples said in an interview that three new faces have pulled nominations papers for the Board of Selectmen and they have until March 25 to return them. They are Keith Purrier, Steve Schoonveld, and Vic Leemon.
