There once was a horse barn that had a new concrete floor in a portion of it. The owner planned to cover the concrete with Tire Veneer, a rubber roll material. The installation was loose lay without adhesive. The material arrived on Thursday and one half of the concrete was covered on Friday. The installation crew did not work over the weekend. When they returned on Monday, they discovered the horses were standing on the rubber portion and not on the concrete. This Indicates that it may be less stressful to stand on rubber than bare concrete. Voting with their feet!
