Had a private event here in the evening, and I really enjoyed it. It's a nice little place full of Wells Fargo an Wachovia history, so of you're interested in seeing how banking has evolved through the past 100 years this is a nice stop. It's not too big, but has enough to do to keep kids and adults entertained for about an hour.
I really enjoyed the picture spot in front of a real stagecoach. The museum has a digital camera that will email you a copy of the photo, as well as prints out a hard copy to take. You can also 'put your face on money' at another photo station, pan for gold in a tabletop touch-screen game, and ride in a stagecoach with scenes of wilderness rushing by. There's also a small 'coin operated' stagecoach kiddie ride that only requires the push of a button to operate, which would be really cool if I was about 25 years younger :-) .
