Be sure to visit Personal Touch (The un-official Ridgefield welcome wagon aka Dee.) She's a friendly lady who stops by and gives you a ton of useful information about the town, recommendations and a thick packet of flyers from local businesses. Her visit takes about one and half hours, and well worth the time.
Also, if you like to socialize, be sure to join the Ridgefield Newcomers Club. Since 1967 they have made new residents feel welcome and part of, which is always a good feeling.
