When I camped in my truck on the fairgrounds, I got cleaned up thoroughly before the
show opened, but that was before coin showers and paying to camp. This morning, in
a Sam's CLub, at a different location in another city that the above Walmart, and noting a row of 18 wheelers parked with engines running, I asked if they permitted overnight stays. They said they did, up in that corner of the lot with the big trucks.
There are Walmarts in Gettysburg, and south down I-83 at Shrewbury. The Sam's
off Memory Ln. will have the same hostile rules as the Walmart there, but I do not
know about Shrewsbury or Gettysburg. I have camped at a campground at Gettysburg
and outside Carlisle, but they are not exactly handy to York. Have not kept up on my KOA guides to know if any of those are closer than Gettysburg.
