Apparently they will be recording who is present so that service hours will be correctly applied.
Two time slots are available - 9AM to 12 Noon or 1PM to 4PM. It was asked that if you and your son plan attending, please RSVP to krista_dustin@hotmail.com, as soon as possible, just so that they can have an idea of how many people will attend each session.
Again, from a Cub Scout standpoint, if you are planning on attending this anyhow, wear your uniform - it is good Public Relations for the "Most Active Pack in Mayfair".
