Happy (belated) 50th birthday to Hardee's! Founder Wilbur Hardee opened his first location in Greenville, North Carolina, on September 3, 1960. You can read more about the history of Hardee's at tesg's guide to big chain road food consumption.
To celebrate the big 5-0, Hardee's is having giveaways all month, including daily $50 gift card giveaways on Twitter for answering trivia questions or checking in on Foursquare, and $10,000 giveaways (among other prizes) on Facebook. On September 30, they'll sell their sausage biscuits for just 50 cents. For a description of all their birthday promotions, check out hardees.com
I quite like the Flickr set they've made featuring retro photographs, ads, packaging, and more.
