You can't find a more generic town than Great Falls Montana. This comment is meant as neither good or bad.
The life blood of this city is the multitude of small agricultural towns that surround Great Falls and of course the Malmstrom Air Force Base.
Great Falls has the usual amenities of the major national chains of stores & restaurants. While spread out a bit, Great Falls is very easy to navigate and I find you have to actually try hard to get lost in the city as the streets are well organized and numbered logically.
There really is nothing overly good or bad about Great Falls. I compare it to a generic store brand product. Nothing fancy but it gets the job done.
