We're promoting outdoor recreation--running, hiking, biking, swimming, camping...hang gliding, you name it--for all of June. Submit your fun photos to show others in the community what you're up to. Winners will be chosen frequently throughout the month to receive a free book.

You can submit other photos of green living at any time.

Please note: To meet our criteria, the outdoor recreation must be non-motorized.
