I'm completely new to touring, but I'm looking to do some long-distance transportation this summer on my bike.
My question is, how do I plan my route using a normal road map, as many of you seem to do?
Of course I know to stay away from interstates, but are divided highways sometimes okay or always a no-no?
Are federal highways bad and state highways good? Or is it less simple than that?
On the AAA maps I have, red lines are "primary" roads while black lines are "secondary" roads. Some of the reds are state, some of the blacks are federal. Do I choose black over red, or state over federal? Is there a different, better way to figure this all out?
Any advice on different brand maps I should be using?
