Whether I agree with it or not (which I won't get into)....to be honest, I don't think its logistically possible to have that many extra volunteers.
Assuming a 40 team regional, you would need 7 extra volunteers for three days. Multiply that by 26 regionals, and you have 182 extra volunteers necessary.
Plus, at the Championship, with 281 teams, you would need 47 extra volunteers for three days (that's rather creepy, if you ask me

).
Look at it this way...at some regionals, this could be somewhat plausible (esp the ones that are funded by major companies)...but even at other regionals and
especially at Nationals, those volunteers are really hard to find. I mean, if it takes Aidan to put a post on Delphi because FIRST can't find crowd control volunteers for Nationals, then we're already hurting for National volunteers.
My suggestion to fix this? FIRST should ally with an airline and/or hotel to provide discounts to these volunteers to get them to schlep all the way down there. If Nationals was in NH, we wouldn't have such a problem with this - because the large volunteer base is already established...and no offense to GA, but it's just not at the level to NH in concentrated FIRST non-team support (please correct me if I'm wrong in this statement, GA!). Thus, the majority of people that are traveling to GA are helping out their teams - not paying hundreds of dollars to work for free for a couple of days (though I have done that before - and it's fun! I'd recommend it to anyone).
But that last paragraph was rather OT.

Anyway, whether it is right or not to watchdog teams, logistically it is a major challenge. Thus, the most efficient way to do this would be to trust your fellow FIRSTer.
