I love Bluegrass and early country music and am something of an aficionado. I attended the first few multi-day Bluegrass festivals, centered around the career of Bluegrass founder Bill Monroe, in Fincastle, VA in 1965 and '66. A few years later, as an undergraduate, my room-mate and I attended Bill Monroe's "Brown Country Jamboree", in Bean Blossom, IN, one week-end.
A surprising thing happened at Bean Blossom. We arrived in the middle of torrential downpour.
