Just-in-time delivery doesn't allow for any hiccups in the supply chain, so it's a great question.
Just-in-time delivery means that everything has to work perfectly or else something backs up, or else there has to be some capacity in the supply chain.
I'll say there is a little bit of fudge or capacity in all areas of the supply chain right now. We've added tremendously on the rail side and there are extra warehouses being built, and the ports have actually done a great job in trying to find extra places to put containers coming in. However, as soon as there is a bubble in the supply chain, it does create major problems, and that's what we've witnessed.
