  23. Liberty Station Public Market (San Diego)
    Static
    Take a walk inside (with a craft beer of course) and walk through the market. There are various restaurants serving up Thai food, empanadas, Mexican, Italian, etc. also great bakeries, butchers, and bicycle shops. The rest of Liberty station is great to ride a bike, take a run, catch a movie, and grab a cup of coffee.
