We had a busload of 49 senior citizens tour our house at 11 am. (Much more difficult than just kids,)
Many years ago I had busloads of school kids coming here, every night after school. I had some of the same teachers with the various groups .. . . . so each night I had to think up a new way to scare the teacher..again.
This was lots of fun!
The school (20 miles away) had a report card for each kid based on a points system and the rteward was to be those trips here. The administration guessed that not many kids would perform this very well. THEY WERE WRONG! Instead of the teacher estimate there was instead about 5 bus loads who did what the had to to get the score needed!
