I visited the Bechtler, Gantt Center and the Mint and this was my favorite. I thoroughly enjoyed the permanent collection and my sister and I received a private "tour" from one of the security guards. You're allowed to take pictures of most of the art. It was beautiful!
They were installing a new exhibit focused on the 1893 Worlds Fair that I'm dying to see. Hopefully I'll get back for that.
FYI: you get admission to both locations for the price of on for 48 hours! Enjoy!
