I don't know if the WEIO (world eskimo indian olimpics) will be going on while you are in AK but if this is the year for it make sure you find out what city it is being held in and attend it. We did not make reservations befor starting on the trip but when we go close to Danalli we called ahead for reservations and that worked for us. We used the PULL OUTS located all over AK for inromtu campgrounds and camped in real campgrounds about once a week for clean outs and a long shower. Like someone already said Buy a copy of the MILE POST aahead of time kand read it it will really get you excited. It will also help you identify where you want to go.
