Those visiting the Santa Barbara Mission don't always realize that it backs up on beautiful, oak-lined Mission Creek, or that you can stroll along the creek and wander across a stone bridge into the Santa Barbara Museum of Natural History. In the Summertime, the Museum campus literally comes alive, with a live butterfly exhibit and one festival after another. At other times of the year, the setting is still so beautiful that it's worth strolling the grounds and visiting the gift shop. That said, unless you have an undying interest in viewing dusty, out-dated dioramas filled with stuffed versions of once-wild animals, avoid the Museum's standing exhibits. One display contains a preserved rattlesnake with a push button on the outside of the case. Guess what happens when you push the button? Yes, the tail rattles just like it did decades earlier when the exhibit was first installed. The connection just looks a littler more rickety than when first installed.
