How could that specific problem have been overcome?
Could I suggest that each child of school going age be State provided with heavily weighted , spiked lead boots which would keep them upright in the breeziest & snowiest conditions with perhaps the addition of a small , mobile heater which could be attached to their heads ?
Teachers should have no problem getting to schools in their 4 wheeled drive mercs & on alighting from their cars their bulging wallets should keep them firmly anchored to the ground.
Sorted !
