Having hiked in areas with 1% maps, and having hiked in areas with 101%
maps, I have to say that I prefer the 1% map.  With the 1% map, there's
at least no question that you're off the map and on your own for
route-finding.  With the 101% map, it's very easy to get in trouble
because the connecting trail you were counting on doesn't exist.
