Wouldn't it be nice if a few states had heritage reservations where the development of technology is set to a time frame?
The Amish do a wonderful job keeping it old fashioned, but it'd be nice to see 1770s , 1860, 1900, 1950s, 1970 the size of a township or two.
It is good to preserve the old ways because you'll never know when that kind of knowing will be handy.
Also these limited technological counties could be a real tourist draw.
Of course it would not be illegal to have modern technology but only for emergencies. There are plenty of people who wouldn't mind living in the 1950s or 1800s with horses and all.
It doesn't have to match exactly but wouldn't it be nice?
