Los Angeles - Griffith Observatory. The view of LA at sunset is breathtaking and the museum is interactive and up-to-date with the best space-science has to offer. If you want to see the planetarium you must also plan ahead to reserve tickets. Free to the public and open late, the observatory is an LA evening must.
Palisades Park, Santa Monica Ca. I always loved this park. I remember my grandparents always taking us here. Once when I was 2, My Mom had my portrait drawn here by an artist in the park, a chalk drawing. My Dad still has it.
