  Same here.  But the interstates generally parallel the old roads.
  I recall several times on my trip last year I would be RT 66 and just off
to the side was I 40 (?).  It was  bumper-to-bumper, 80+ mph, full of semi's
and I was the only one on 66, cruising along around 50 mph and enjoying the
ride.
  I did like putting in a search "driving time from X to Y" and that would
give a general idea.  It followed the interstate and I just added some time,
depending on the distance and terrain.  A hour here, an hour there, etc.
  Google maps came in handy when I stopped for the night.
  I would write on a sheet of paper things like "(RT) X to Y, then
left/right, etc.  That way I could quickly glance at the sheet for directions rather
than looking at a map.
  Its almost impossible to find state maps any longer, like they used to
give away in gas stations.
  However, once in a while I would have to take an interstate and would
stop at visitors centres and get a map for that state.
  The only visitor centre I can recall on an old road was in Arkansas
leaving Louisiana.  I was really surprised to find that.
  I prefer paper maps, you can lay then out and plan a route a lot easier
than on a screen.
