I live in san diego....in a military base in front of the zoo
I will vote for San Diego, one of the most beautiful cities in US.
It is a naval base in the history. Now San Diego becomes the top tourist attraction and wonderful resort area. The weather channel rates San Diego's climate as one of the two best summer climates in America.
Things to do:
1.SeaWorld San Diego, the San Diego Zoo, and the Wild Animal Park
2.Coronado's beach, great place for water activity, picnic, sandcastles, and kite-flying. If you drive, enjoy the beatiful and envious scene of 70-mile beaches.
3.Food is also various. You can eat at the district sections of San Diego and may find lots of every world cuisine.
I personally have been to San Diego twice. Each time I stay more than 10 days with friends. Take the inexpensive shuttle or train looking around the city. You will find the beauty of San Diego.
