Rice's Market (Tuesdays)
Thirty acres of flea market, farm stands and antique dealers going since the 1870s. Gates at 7am and it thins out by midday, so come early and bring cash.
Executive Scramble
Nine simulated holes before work with a rotating cast of local business people. Ninety minutes, no handicap required, and the point is the conversation between shots as much as the golf.
Autumn Avian Adventures: Murmuration & Migrations
A guided morning walk across Stroud's meadows and woods hunting migrating songbirds, raptors and waterfowl. Bring binoculars. Registration goes through Natural Lands, and the preserve itself is free.
