My parents winter in Arizona and would like to see Oregon and Washington "on the way home" to Michigan for the summer. So this would be mid May trip. They have never been to Oregon, Washington or Montana (hence the emphasis on those states). A couple of years ago they did a California coast trip getting up as far north as the redwoods so California is not a "sight-seeing" factor in planning the trip. I know they want to see Crater Lake and Seattle but not having been to those states myself I am finding it a little overwhelming trying to figure out what route and things they should stop to see. I love planning trips and help them with the logistics and giving them ideas of what there is to do. There style of travel is to spend a lot of time driving and a little time stopping to see things. Not the preferred travel method for a lot of people but it works for them. Can anyone help me out with a route to get started on? I did a mapquest and it looks like it shoots them up through California through Sacramento up into Oregon with a little jog over to Crater Lake and then back up heading to Seattle. It doesn't give them any coast time in Oregon or Washington. Having done highway 1 in California will they be missing things if they don't go to the coast in Oregon and Washington or should I route them over that way?
