Bullhorn or PA system?

I know this has been discussed before - but I think one big improvement would be to have a bullhorn and/or PA system of some sort. The bullhorn would come in handy with times such as explaining the Tag Team MX rules to a group of 100 sitting on their bikes. And a PA system would help keep everyone informed, for example, like announcing the Saturday pigout will begin at 4:30 pm and not 6:00 pm as posted earlier. I also thought the addition of the big "activity" board for the day's activities at DW03 was a great idea and came in handy for us throughout the week.
