This is a bigger pile of crap than usual....
I've had 2 kids in high school.....I can't think of a single teacher that would walk a class of HS purple people eaters a half mile to a public library....forget a class of HS kids!!!!
In the first place, schools have libraries and computers...no reason to go to a public library by foot or by car!
In the second....
walking a class of HS students a half mile....half the class would disappear before they ever got to the library.
In the third....no school is going to allow a teach to
walk her class a half mile anywhere these days....the school will not accept the liability and would not allow the teacher to accept the liability.
When my kids were in middle school, 15+ years ago.....at the end of every grading period, the teachers would walk them across the parking lot, down the school drive, into the adjacent parking lot for pizza at Mr Gatti's. They were never even on a public street! and there had to be one parent for every 6 or 8 kids. The school system hasn't allowed them to still do it, in years. The liability was too high.
Geesh Dummies...if you are going to make up a BS story....at least make it believable!
