I cannot go to this, alas, but in case any of you all can: the Pioneer Engineers Club of Indiana is holding their Antique Steam and Gas Show in Rushville, IN, a four day event starting at 9 AM on Friday. Only $5 for Friday, Saturday, and Sunday. There will be a Parade of Engines at 2 PM each day, and on Saturday evening there will be "a spark show, which is a way to use a steam engine to generate 'fireworks'." Sounds exciting. You can get details from the horse's mouth here.
