If you make the trip to Anaheim during baseball season, take a trip to watch the Angels play.  The stadium they play in is one of the most unique ballparks in all of America.  From the large hats outside the stadium, to the rocks in the outfield, to the way the seats are angled towards the field, it is a one-of-a-kind experience.  Also, if you have been to major league games before, soemtimes people returning to their seats in the middle of an inning can be a distraction.  At this park, the ushers will not let you return to your seat in the field sections until an inning is over.  This allows you to always be at ease watching the game.
