Having been at the entire length of the meeting, here are my observations:
At the end of the meeting, a gentlemen named Kevin representing Idaho Rivers United asked for a show of hands for "all of those in favor of changing rapids/rivers," or something to that extent. Needless to say, people immediately demanded a rephrasing of the vote.. To my understanding, it was rephrased to "all of those in favor of doing something about it, rather than leaving it the way it is."
In my honest estimation, about 50-55% of the people raised their hands in favor of doing something (that might be filling in the sieve, that might be rotating the rock, that might blowing the rock up with some explosives.)
Then there was a show of hands for those in favor for leaving the rock the way it is. Noticeably fewer hands were raised. Maybe 35% or so.
Then someone from the crowd said "how about undecided?" And a few hands were raised. Maybe a few others didn't vote.
Again, those are my observations, but I would say without a doubt in my mind that the majority of the voters (if not the majority of all the people present) were in favor of some kind of change.
