I'm with you Pal. I remember about six years ago when we got hardly any snow and had a great ice season we were drilling through through 22 inches of ice, that's the closest I've ever come to having to use an extension. I started thinking about this the other night and was thinking if I was going to get one I might as well as get the eighteen inch extension, just get the biggest and be done with it. But from a practical point of view there's no chance of ever needing an eighteen inch extension here but a twelve maybe and even that's not much.
