Hey guys, I just got back from a John Mayer concert in Clarkston, MI, and while I was there I bought a t-shirt that said "Dig!" on it, and had a picture of a bulldozer. Do any JM fans out there know what this means? I bought the shirt 'cuz it was blue (a good color for me) and I had planned on responding to any questions with "OMG! You don't know what Dig! means?! Everyone knows that!", but it WOULD be nice to really know for myself. Thanks!
