You might have had more than your fair share of Hormel's legendary canned pork product over the years, but you won't know the whole story behind it without a visit to The Spam Museum. Located on Hormel's main campus, this 16,500 square foot ode to Spam features trivia, vintage Spam advertising, displays depicting its use during war time, a tribute to Monty Python, whose "Spam" sketch actually led to the term being used in referral to unwanted electronic communication, and, of course, a Spam store full of Spam collectibles. And while Spam might not be free, admission is.
