I'll add that one of the things we saw in exploration is that in Minnesota they have created a program that pays production incentives for production of biochemicals from a cellulosic base—so, wood fibre. It's a fairly substantial production incentive when you look at the price of the materials they are trying to encourage. While that's not a tax incentive, it's something unique that I haven't seen done elsewhere. What I like about it is it's very targeted at trying to use more wood fibre.
I'll be happy to provide details on that if that would help.
