BATH — There’s a crisp character to the air that can only mean one thing: Autumn has arrived.

With autumn comes pumpkins, leaves changing, hay-rides, cider, apple picking, and in Bath, Autumnfest. The annual event is running this weekend and closing down North Front Street to feature an afternoon of fun and games.

Kick things off with a morning jog in the Bath Rotary 4-Way 5K at 9 a.m., at the Knights of Columbus building, 807 Middle St. There’s a preregistration fee of $20, or $25 the day of the run. For students 18 and under, the fee is $10. For more information, visit www.bathrotary.org.

One of the most popular events at Autumnfest is Citizen Involvement Day, where over 40 non-profit organizations assemble in Waterfront Park to share information about their organizations. A key feature is the annual Citizen of the Year, Community Spirit, Community Project, and Youth awards. Past winners of Citizen of the Year include Brian Hatch, Leslie Trundy, and Kimberly Gates.

At the same time, one of the last outdoor Bath Farmers Markets will happen at the park, too.

Up at the Customs House, the annual Great Scarecrow event invites people to make – you guessed it – a scarecrow. While they may not get use scaring pests away from crops, they’ll definitely serve as a great activity for young and old alike. The event runs from 9:30 to 11:30 a.m., and the Bath Parks and Rec department will supply the body frame, hay, and markers, but you have to supply the clothes and accessories. For more information, call 443-8360.

Throughout the day, local businesses and shops will be holding special sales and rewards for shopping locally. If you’re lucky, you can receive a Gift of Bath certificate, which will allow you to shop in any local businesses that participate.

Up on North Front Street is where the biggest party is going on. The street will be closed off, and features a Business Pumpkin Decorating Contest, pumpkin bowling and tic-tac-toe, coloring contest (sponsored by Sunnybrook), apple bean-bag toss, a concession stand hosted by the Bath Youth Meeting House and Skatepark, and a live steel drum band.
