Every time someone new comes out to the farm during wet weather, I always warn them about the border around the gravel pad. It is made out of 12" diameter cedar barn logs. They get very slippery when they are wet.
So despite knowing the hazard, I managed to step on these (with rubber boots on, no less) and took a spill. With a full bowl of hog feed mash in each hand.
I was ok, other than some wounded pride and a mash covered sweater.
It only takes a heartbeat to end a career or incur a dry cleaning cost.
BE SAFE!
