Hi again,
Do you have a GPS unit? If so I can give you cord. to a few places. Until then, on Armstrong Rd, there used to be an old building. I've heard it was a cider mill or an old school. Not sure which story is true. It's now gone and part of a farm field, so permission would be needed. If you go there you can see where the road used to be right along the cliff next to the river. The cliff started to give way, so they moved the road over some. the old building was in the small field that was created between the old road and the new one.
Also, check out the Delaware historical society. it is on the corner of E. William and Little street. It's a great place to get ideas.
Let me keep looking. Where in Delaware do you live and how far are you willing to travel?
