It seems to me,what they do before entering school property is none of the principal's business anyways (school property includes school busses,mind you,but come on...). I,my Dad,and the principal of my high school (back in my senior year of 1991
) had that discussion twice...te one time when I rode my YZ250 to school via railroad tracks (the teens highway back then,we all had some kinda bicycle,dirt bike,or ATV,LOL),and another time when I got into a race with my HS nemisis and we both passed him during the meat of it on the highway
I think they get all full of themselves,personally...but then (with the exception of my ARMY days),I have issues with anyone who doesn't sign my paycheck thinking they have authority on me anyways (and I'm kinda "retired"
)
