The Potassium Chlorate needed for Boomershoot 2011 Boomerite was delivered to my home in Idaho a few hours ago. Assuming the ground dries out enough to get it to the Taj Mahal by the end of April we just need some more target boxes, a few gallons of ethylene glycol, and the mystery ingredient (readily available from Costco in 50 pound bags) and we will have all the supplies we need for the next event.
