JAX is an interesting destination. I flew into it about 10 years ago for a conference "downtown," and the cab ride took nearly an hour as I recall. The downtown was not very dense, a few tall buildings but very little street level activity. There was a waterfront entertainment venue that was mostly empty on a Saturday afternoon. From the air, the city seemed to sort of sprawl off in every direction for miles.
Anyway you could theoretically drive to Savannah or Orlando in about two hours from JAX, so it could be an appealing option for some people.
