BITD of paper maps, one could become proficient in predicting, road type/pavement, traffic volume, and terrain off maps. My favorites were from Rand McNally, whose road codes is where the expression "blue highways" comes from.
These days, I use my old maps to get a general idea, then various online sources. Google maps is nearly useless for long distances, but can be excellent for shorter legs, and they also show bike paths. So once I've blocked out the big picture, I'll use Google maps to fill in details.
