For those of you worried about mosquitos and chemical exposure there are some very good natural bug repellants on the market now. My wife and I live in Fairbanks, Alaska which is mosquito heaven, and we use only organic/natural repellant. It works great, and we don't have to worry about the exposure to high levels of Deet.
To the OP- Great Blog!! My wife and I are going to do the Dalton next year after our FJ is set up a little better. Of course its a bit shorter trip for us, but still just as beautiful.
