When is too many at a glider meet

I recently learned that Bruno has increased the number of gliders for the Nephi, UT event to 80. That's right, eight zero. IMHO, that is too many, even if FLARM is mandated. There will be pilots there from virtually zero cross country time to seasoned racers. They may be lulled into a false sense of complacency until a storm forces the entire field back to the airport at once, creating chaos. I get the bad feeling that this number will keep increasing - or stay the same - until there is a fatality.
