Dave Barnes is fascinated by my phone. It’s tiny and red and looks very much like someDave Barnes type of voice recorder, and when I tell him it’s really a phone, he exclaims that it’s the coolest thing he’s ever seen. He’s also impressed with my new Canon L-series lens…not necessarily because he knows what it is in terms of luxury lenses, but because it’s big and weighty and in his estimation could probably spot Jen (Anniston) and John (Mayer) in LA from where we sit on the other side of the country. We are sitting at an outdoor picnic table underneath the main deck of the Windjammer in Isle of Palms, SC. Barnes is sharing the stage with Matt Wertz at the Windjammer later in the evening.
