Augusta is a very fun town and very military friendly. I lived there for 5 years and we found that while they appreciate Ft. Gordon, it is not the lifeblood of Augusta. There is a lot of other stuff going on in the area as opposed to being just a "military town."
Lots of good nightlife...people go out every night of the week over there. I guess that could be good or bad depending how you look at it.

Very decent shopping there...about anything you could really want. Restaurants on every corner...Augustans LOVE to eat out.
That being said, like any medium sized city, there are some areas to avoid at night but I think anyone local can probably point those out to her.
DH and I would move back there in a heartbeat. Hope she has a great time!
