I'm planning to be there as well...and I haven't been to a launch in at least a year and a half, maybe 2. I told my kids that I want to spend father's day flying rockets with them. I hope the weather holds out.
Amazingly we had about three dozen slightly crazy folks so up despite the weather, and got 61 launches off before the steady rain arrived after 1 PM, ranging from micromax to a G saucer. Most kept it below 500' so they landed in in low grass although a few brave souls found the 6'+ hay and the 80' trees downwind of the cut grass.
Since CMASS paid a non-refundable field rental fee of $180, President Bill Spadafora came prepared to launch even if the field was underwater! The field was actually in good shape, but Bill, to prove his point, made not 1, but 2 underwater launches! The launch pad was a custom micromax pad in a 6" diameter flower vase. The waterproofed rockets were wired up, continuity checked, and the vase filled with water covering the rockets by 6" or so. The launch button was pushed and the motor ignited and the rockets flew out of the water. It was pretty cool. Bill took 60 fps DV so I'm sure he'll post the videos.
