August! It's the dog days of summer and the one month of the year without a major holiday. But just because your local mattress dealer doesn't have a silly costume to get into for a big sale this weekend doesn't mean you can't celebrate MUSTARD DAY! That's right, Mustard Day was established as an annual event in 1991 by the National Mustard Museum in Mount Horeb, Wisconsin. ROAD TRIP! ROAD TRIP! ROAD TRIP!
