Trick or Treat
East Caln Township sets its trick-or-treat window on Halloween night itself, six to eight. Township addresses carry Downingtown 19335, so this covers the neighborhoods just east of the borough line.
Around the same time
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.
Bird Walk at Peter Wentz Farmstead
An early walk across the farmstead fields and nature trail with the county environmental educator, looking for whatever came through overnight. Free, but email ahead to register.
