From 2008 to 2013, I organized several regional photowalks, primarily two-mile loops through scenic parts of some of our area's towns. As the weather starts warming, you can grab my participant maps when you want to get some exercise and fresh air.

You can download maps for Gettysburg, Columbia, Lancaster, New Oxford, York, and Harrisburg. Find a friend and use that cellphone camera!
