The Bridges of Lancaster CountyLancaster County is known for having the most covered bridges out of any county in Pennsylvania. Most websites I checked said that there were 31, but I'm pretty sure flooding this past fall has lowered that number.
I normally don't get overexcited about the covered bridges (there's one right outside where I work) and have never gone trying to find any (the link below has their locations) but I know some of you are into things like that.
I was driving back from a hike on the Susquehanna yesterday and did cross over one, The Coleman Covered Bridge which is the second longest in the county and was impressed in spite of myself.
