wait till after lights out
we use to drop more than logs in there them to wake up them sitting there after lights out and see them run with their belts around their ankles
i did my trade as a diesel fitter in my states railways and on a test run of an L class loco just out of the geraldton workshop we hit a bull and i bet we did as much damage as a mortar to a sheep
tho ive seen worse carnage ill keep it at that
