Saw this sign on a streetpost on Forest Avenue the other day... what does it mean? I have to say, it doesn't give bicyclists a good name. It's one thing to add hula hoops to a pedestrian, but machine guns to handlebars? Anyone seen this elsewhere?

This great fall weather has meant an extended biking season, especially for mountain bike riders. There are still races and bike events taking place, including one fun one for a great cause: the Great Osprey Bike Challenge on Sunday, Oct. 28.

Planned as a family event, this race on tar and gravel roads takes place on and around the grounds of the lovely Wolfe's Neck Farm in Freeport. There's a short course of 4.4 miles (the "Mild" race) and a 5-lap course for more serious riders (the "Spicy" race). There's great food, a pee-wee biker derby and demos too.

The Freeport Recreation and Community Education department puts on the event and proceeds from the $15 fee go to a scholarship fund.

Fall foliage season is upon is and there's no better time to get out on the mountain bikes and into the woods. If you haven't biked up in the Carrabassett Valley, then you really should get up there this fall. There are great trails that serve to remind you just why you live in Maine.

The Bicycle Coalition of Maine holds an annual Fat Tire Frolic in Carrabassett Valley, and this year's event is on Sunday, October 7. Here's how the BCM describes it:
