As a masters student, the school expects you to write a thesis on specific subject. Since most of my time with history involved working in a museum, I decided to go the public history route. Instead of writing a long paper that no one will read, I am creating a free walking audio guide tour of Balboa Park. The idea came to me when on a recent trip to Europe with my Wife we listened to audio guide tours by Rick Steves. These tours were great and provided just enough details and with that we walked away learning something.
