Last summer there was a fellow playing bluegrass banjo down on Pittsburgh's Strip District. He attracted a fiddler, and then a mandolin player, and soon enough there was a whole, impromptu bluegrass band playing on one corner. They had a fiddle case out for tips, and I gave them money, because there just isn't anything much nicer than bluegrass on a summer morning. It was all I could do to keep from dancing. I expect all of them had straight jobs, and they used the money for beers at one of the strip district's bars. I hope they'll be back this year. I need some good bluegrass right now.
