Louis Molinary is convinced that the Stones wouldn’t really care if he wasn’t able to make his mortgage next month.  The fifty-something real estate developer from Charleston, SC  is quick-stepping into the festival alongside me, headed back to the picking tents.  He tells me he’s new to bluegrass music and wants to hear some more, he said.. Until last year, when a longtime friend finally convinced him to come, Molinary had been more of a fan of The Rolling Stones, and Led Zeppelin.
