The Think Big Column in our magazine is a regular platform for some of the most remarkable sights along the American Road. Erika Nelson is the peripatetic folk artist who chronicles kings and queens of the highway like the largest ketchup bottle or biggest baseball bat in the World’s Largest Collection of the Smallest Replicas of the World’s Largest Things. In this conversation Erika shares her most recent find: a titanic turtle that is displayed in our Spring 2014 issue. How does she find these roadside behemoths? You’ll just have to listen to our conversation to find out that and much more.
