From my "infrared project" -- this is one of the two images that were just accepted into the Schuylkill River Heritage Area juried show in Pottstown, PA (out of three submitted). Since it was up against paintings as well as photos, I am pleased it got an Honorable Mention.
This is a former Pennsylvania RR bridge across the Schuylkill River. The RR grade is now part of a multi-use trail that is well on its way to reaching from center city Philadelphia to Pottsville, up in the anthracite region, approximately 100 miles, now maybe 60% or so complete. More selections from several Schuylkill Heritage Area expeditions may be seen at:
