What are your interests? The Museum of Fine Art, the Science Museum, the Historical Society, the State Library? All are OC friendly. Hollywood Cemetary has lots of historical figures planted there, as well as the bodies of folks who you read about in your history books (statues & people). Monument Avenue is worth a riding tour to see all the second-place trophies. (I'm a Yam Dankee - what did you expect?)
What do you like to eat? We've probably got at least 2 places that are OC friendly, unless it's German (can't find one place, friendly or not, in town ).
The best thing is to let us know when you are planning to be in town so we can see who can free up their schedule to meet up with you.
