Since you're referencing my pics and RR then I'll chime in. I didn't mind buying the maps and converting them. It kept my mind on the trip and aware of the different towns we'd be passing through as I was plotting. Also, the rerouting in Oregon is something that will be faced no matter how he tries to update the route. Most of the roads are logging roads and thus change on a regular basis. The good thing is that there are tons of available roads to use to get where you need to go. Overall I think the whole process of planning a TAT trip is exciting and a great learning experience. The GPS plotting is all part of it.
