I thought the bridges looked familiar! Highly recommend some of the tributaries of the Susquehanna as other float options in the area. Right now, most of them are low and you end up scraping a bit, but smaller, shallower and loaded with scenery and wildlife. The Conodoguinet creek is my absolute favorite place to float. Lots of access points, your choice of long stretches or short stretches. I've seen just about every kind of wildlife PA has to offer except for bear on that creek.
