One of the things is the transition, if you will, and the confidence in a transition. I'm thinking of discussions around using different types of material for my grain dryer. Currently, I use natural gas and it's a bit of a challenge when I'm taxed on it. It takes away my ability to make any kind of a switch, so that's a bit of a challenge. It doesn't work that well for me, to put it gently.
I don't know, Dave, if you want to contribute on that too.
