Is the Art & Jazz Festival in Grand Junction worth visiting?

If you like art and jazz, sure! :)

In all seriousness, I'd definitely recommend it. If you want to experience some great, local Colorado music, art, wine, and food, this is a festival that highlights them all. You can enjoy at least ten bands over the course of three days, art on every corner, while also appreciating all the local breweries and wineries have to offer.
