We visited Moab last year and somehow missed this. We are so glad we went this year. It's not a large museum but has loads of interesting exhibits all about Moab and the surrounding area. The staff were very friendly. A special exhibition entitled New Harmonies had just opened when we visited. It was all about the history of american music and was really interesting - it has been touring Utah and other states and finishes in January 2011 so try and catch it if you can: http://www.museumonmainstreet.org/newharmonies/harmonies_sched.htm
The museum is just along the street from the Moab Information Center and there is plenty of free parking nearby.
