LEVERETT — An apple bike bake-off and pumpkin decorating contest, along with 20 arts and crafts vendors, will be part of the Leverett 250th Fall Festival on Sunday, a culminating event for the town’s 250th anniversary year.

Beginning at 1 p.m. at the Leverett Elementary School gymnasium and in the parking lot at the 85 Montague Road site, the three-hour festival will feature music, games and free pumpkins to decorate. Admission is free.

The homemade apple contest, open to amateur pie bakers, requires that people use both homemade pie crust and filling made using locally grown apples. The appearance, crust, filling and taste will be judged by local food writer Claire Hopley and friends, with the top three entrants earning prizes.

Already decorated or painted pumpkins brought to the festival are also eligible to win prizes in several age categories.

Among the vendors will be people selling pottery, paintings, hand-painted shirts and cellphone pouches, goat milk lotions and soaps, cards, painted glassware and birdhouses, local maple syrup, CDs and tooth fairy pillows.

Books by both Hopley and Steve Adams, another Leverett writer, will be on sale.

Live music will be provided by Masala Jazz, and DJ Overtime will be spinning records with songs from the 1950s on.

In addition, the festival will be a final opportunity for people buy souvenirs and T-shirts commemorating the town’s anniversary.

Information and activities tables will include those from the Leverett Library, the Leverett Fire and Police departments, town nurse Sarah Fiske, and garden and kitchen tool sharpener Ben Goldberg.

There will also be free refreshments and s’mores.
