San Diego travel tips
1) Do you want to see the 600-year-old Inca Goblet in San Diego? | Head to the San Diego Museum of Us, which is housed in four beautiful Spanish colonial-style buildings. Here you will learn about pre-Columbian American history, Native American culture, and Mesoamerican civilizations such as the Maya. One exhibit deserves special attention — a massive golden beer goblet that belonged to the Inca king about 600 years ago. The admission is just $20. |
|---|---|
2) Do you smoke? Pay attention to signs in San Diego | Watch out for prohibition signs in San Diego. You can smoke there only in specially designated places.
