I saw this sign in a Thoroughbred farm's barns in Paris, Kentucky recently. Notice that this is a mass-produced sign. Are these seen in other parts of the world? Other places in the USA? I had only seen signs like this (and not "storebought" one, at that) in equine hospitals until this spring's trip to Kentucky. The funny thing was that the farm did not have a sprayer, it had a wet mat. I guess no one has manufactured a sign for wet mats yet.
