Did Osh last year. Just drove in for the day.  I remember if  you wanted an ear of sweet corn it was $8 each.  Don't remember hamburger prices. Yes, bus service from parking to main entr. was good.  Did not stay for evening.  I was to tired from all the walking, but I was 69 then.  My wife who does not care about mech things enjoyed seeing Osh.  I was a flyer 25 years ago, so I enjoyed seeing all.
