The Rose Bowl happens in Pasadena. The Flea Market is only once a month, its usually the second Sunday of the month. Its a great place to find vintage clothes, antiques and rare treasures. I once found an amazing David Hamilton book that I bought for $15 when it was worth $500.
You have to cross this bridge when you're driving to downtown from East LA. It gives you an amazing view on the River, old industrial buildings and the high rises of downtown Los Angeles. Remember that famous scene from Grease? This is the place. I'm still trying to figure out how to get my car in here.
