Though it's not strictly river-related (and thus probably shouldn't appear on this board), a real live Nichol-built steam-powered calliope will be played in Milwaukee's Great Circus Parade on Sunday, July 12. Two regular posters, Dave Morecraft and myself, will be the ones issuing forth steamy renditions from this vintage instrument. The parade starts at 1:30 PM on the Lake Michigan waterfront and goes til about 4:00. I hope some of you can make it!
