Lots of old factories that could be made into ranges.
My best guess is that most of us just do not have the funds. Why could we not get more rich guys into the hobby? But then how many of us just do not support what we have. And the kids are not doing anything that does not have a very quick fun factor. It is why so many hobbies are dying.
It would be nice if there were legislative mandates that every county have at least one range for the purpose of training people in preparation for serving in the military (NRA was formed after the Civil War because so many soldiers from the urban areas were horrible with firearms. The south was far better marksmen)
I don't think they really cared when they surrendered.....
