Ya know, you havent been looking to well lately, and could be coming down with something...I'm just saying that some preventive theraputic sick leave might prevent the children from having their beloved teacher overcome by an extended illness. Or, as previously suggested, there are many academic principles that can be gleaned from a field trip...Gyroscopic effect of wheels, inertia, centrifigal force, transfer damage from impact, and the list goes on. I think the education of these kids is a priority, bring the little crumbcatchers to the track!
