well since multiple battles where fought in the same place, it shouldnt be to hard to preserve hallowed sites.
when you fly over the u.s. you realize how much empty space there is and what a large country we have.
then you hear that someone wants to build a walmart at gettysburg.im all for free enterprise,but not there.
I went once to Gettysburg by car, it's really worth seeing and I also appreciated the 1/1 scale museum. Hope it will be preserved.
