We ran over 400 runs of SG down Hangman's over the last three days without serious incident. Note that the kids were averaging 35 to 45 mph down the course (i.e. up to 65 feet/second). Given that the top and bottom of the course are pretty flat, that suggests top speeds approaching 50 mph or better. Not too bad.
Thank you to all of the volunteers who helped this past weekend. We, literally, couldn't have done it without you. Results can be found on the My USSA web site (login required).
