The Mesa Historical Museum has an exhibit up on the history of baseball in Arizona, including the Cactus League and even before then. Saw an article in a magazine about it and it looked pretty interesting. It's supposed to be running through the end of the years, so I'll have to convince mrskishi to make a cross-town trek. Anyone seen it?

The Mesa Historical Museum is located at 2345 N. Horne Street in Mesa AZ. During the summer, it's open Tuesday through Saturday, 9AM to 1PM, and admission is $5, $3 for children age 3 to 12.
