I really enjoy when I am traveling or on the road visiting smaller museums. Museums that specialize in a a particular area or just the major museum for a small to mid-size city. They often provide exciting new discoveries. The status quo being that the biggest institutions get the most attention it is refreshing to see visit a museum that is not generally on everyones radar.
Ones that I have found worth visiting over the years.
