Shoo fly pie??

I was sure I would find my answer here, but they only came up with one review and recipe of Dutch Corner.
I recently was in Philly and wanted to do a hunt that I took 35 years ago when I spent a summer in Maryland. We drove up to York PA and hunted wet and dry bottom shoo-fly pies. Figuring it is much easier to drive through PA than Arizona, I started googling and looking and hitting all the shops within a reasonable range of where the beau was working for the week, in Wilmington DE. The closest I found was in Lancaster county, and it was too long for his schedule to be without a car. I did find one site that would ship me one for $30 or so.
BUT it seems like such a road trip necessity...
I was in the Reading Station on a TUESDAY, not a Wednesday and apparently missed the PA Dutch vendors.
Instead of running like a chicken, is there any one who was lucky enough to find any of these molassasy gems within an hour or so of Delaware/Philly? I will send the boyfriend out on a run if I can guarantee success next trip!
