Bright moon over Cypress mountian

I had a peak at the web cam at 4:00 AM this morning and said how can that be? How can the sun be that high in the sky already when it's still dark out? It's not the sun it's the moon. Sometimes on a clear night the moon is so bright it casts a shadow on things. Full moon is March 3rd. You can see the lights from the city and the bright waxing moon. Nice.
