Jacksonville is an old mining town, one of the first European settlement in the area. It's a small town, even smaller than Ashland. It is well maintained with a frontier, old west town kind of theme. Popular for tourists, with nice restaurants, artsy gift shops and antiques. Jacksonville is also the home of the Britt Festival, which is a great venue for music and performing arts that has shows every week for the whole summer season.
I've been to Jacksonville numerous times, though I only had my camera on a few of my visits
