As someone who both lives in Veneta and  also enjoys the OCF I find Luann Kloehn's letter rather sad.  I can believe that most everything she says is true, and also that these things bother her a great deal.  I live close enough  myself that I can hear the late night revelry even prior to the fair.
At the same time I'm aware that most "mass gatherings" cause disturbances to neighbors.  Quite some years' past I lived on 13th across from the Lane County Fair, and that caused a terrible amount of late night noise and disgusting littering.  But they cleaned up their act-- limited the noise and alcohol, and even offered free tickets to neighbors. 
While the OCF does offer cultural grants to area schools,  and brings a lot  of money in to town, there is much they could do to make life better for neighbors who are most impacted.
Now, after saying all that, I must say I had a great time at the fair, and appreciate the  friendly folks who made this old   fellow feel young again.
