Oh, I understand what you where trying say now John, indeed that makes a lot more sense.
The way you wrote it I thought you were indicating the survey was done by school district 166 in KS.
" A few days ago 166 school district bus drivers" If you would have made district plural, I don't think I would have misunderstood. But don't take it personal, I can't even spell my way out of a paper bag and I have a masters degree in Elementary Ed!
