 National Onion Day. I'm a big fan of onions. Onions go with just about everything. I agree. Except it does not go well with ice cream cake, but it is Ice Cream Cake Day. On this date in 1829, 195 years ago today, British scientist James Smithsonian died, but he left his entire fortune to the United States in order to establish the Smithsonian Institute. Boy, oh boy.
