A torrential downpour sent revelers sprinting for cover and tried to put an early end to the fun at the Windham Summerfest, but the teens and vendors who emerged from under tarps and dripping ponchos said it had been the best Summerfest yet.

“Last year, there was like, no one here,” said Andrea Feeney, 12, who came to hang out with friends and watch soccer games. Her friend Anthony DeRice, 13, said the best part of the day was the parade, which he was in.

The day began with a pancake breakfast at Windham Middle School, put on by the Lions Club, followed by a parade at 10 a.m., bicycle rodeo at 11 a.m., and skaters competition at 1 p.m.

A frog-jumping contest (bring your own frog) was scheduled for 3 p.m., but shortly before that, the sky turned steely gray, wind began blowing, and thunder rolled ominously. The majority of festival-goers headed for the gym and their cars, while outdoor vendors tried hastily to cover their merchandise.

After a roughly 15-minute downpour, some wary revelers returned to the outdoor booths, but most of the vendors packed up.

“It went very good. There was a lot of people participating and it was well-planned this year,” said Adam Johnson, 15, who was manning a booth for the Windham Drifters snowmobile club.

If the weather dampened the afternoon fun, it did not douse the spirit of the day, which climaxed with fireworks at dusk and the 20th anniversary concert by the Windham Chamber Singers.

Almost 90 current and former Singers took the stage at the Windham Performing Arts Center for the concert. Chamber Singers alumni came from as far as Utah to perform Broadway and gospel numbers.

The concert capped a weekend of music and included the release of the CD “Rising Up” by former Chamber Singer Leah Driscoll.
