I am retired from a 30+ year career in transportation, working mainly in historic preservation. My background is in North American Archaeology, with a PhD from Penn State University, and a special interest in cultural ecology. While much of this blog will be on archaeology and historic preservation, we will necessarily drift into the larger public square of environment and sustainability. P.S. - That wonderful bow string truss bridge in the header is the Messerall Road Bridge over Pine Creek, in Crawford County, Pennsylvania. In 2022, it became part of the Spillway Trail in Pymatuning State Park!
