Hello! We are moving from Central Illinois to the Portland area. We are leaving in about a week. I have not been out of the state of Illinois so this whole thing is going to be all new to me :) ! We are going to go up to Rock Island Illinois and take I-80 to I-84.. What is it like to drive that way? Are we going to be up and down mountains? How is the weather this time of year? Approximately how long of a trip are we looking at? Any input would be great! Thank you!
