Schools in the US are mostly stationary. Students, staff, and teachers enter the building in the morning and leave at the end of the day. If we’re lucky, we may grab some much needed outdoor air and vitamin D at lunchtime or recess, but for the majority of minutes of each day, we’re inside in the same place. Travel changes this. Travel lends that added element of the unknown to the constant of the classroom. For many of us, that unknown becomes a dreaded, scary place.
