Have you ever worried that you're not getting fat fast enough? If so, this Google Maps mashup may be the key to your peace of mind. It's pretty bare-bones right now-- just Burger King, McDonalds, and Wendys-- but there are enough data-points to get you started. Hopefully the author will add all the other fast-food chains soon-- especially the New York hometown favorites-- Ray's Pizza and Gray's Papaya. [Via Kottke.]
