Looking for roadside oddities for your next trip? I recently came across this site that lists the "What's Large Where" by state. Sometimes it's just a name and a city, and sometimes it has more info. For example, the listing for the World's Largest Baked Potato in Blackfoot, Idaho has a link to its website, but the listing for the World's Largest Set of Teeth just says that it's in St. Louis, Missouri. So you might get all the info you need from them, and in some cases, it might be a starting point for more research. Either way, worth a look.
