It's Wednesday, July 17, National Hot Dog Day. Happy birthday to actor Donald Sutherland (1935), who had a small part in 'National Lampoon's Animal House,' and graciously spent time mingling with people during the Eugene filming. Today in 1955, Disneyland, the happiest place on earth, opened on more than 150 acres in Orange County, Calif. In the weather, there's a chance of rain, with a southwest breeze and a high in the low 70s. Here are a few things to do before grabbing a Chicago Dog today:
