There are a variety of weather forecasts for Thursday, so let's do the Brownfield Loop -- it has options for long or short versions that you can choose from, depending on your energy level and on the rain threat.
Meet: Maine Visitors Center, Fryeburg. It is on the right, just over the NH-ME border on Route 302.
Time: Ready to ride at 9:00 am
Distance 32 or 21 miles
Longer option: Cross route 5/113 and get some hill climbing on the triangle loop. 32 miles total
Shorter, easier option: 21 miles (does not include the hilly triangle on the east side of route 5/113). There are options to make this ride even shorter if desired. 23 miles if we check out Burnt Meadow Pond for a lunch stop.
