| In the Garmin US TOPO 24K maps and Mapsource can you search for a hiking
trail name and automatically create a route that follows it?

In the northeastern USA, I have found that hiking trails are often the
least accurate features on topographic maps. A given trail's
representation on a map may have been accurate when it was first added
to the map, but, over time, trail relocations occur and the map's
representation gets out of date. Foot trails in wooded areas can be
hard to spot on the aerial photographs used to update the maps. Newer
hiking trails might not be found on topo maps at all.

In So. Calif, the Garmin 24K topo maps often show newer and more and
more accurate trail location than the latest available paper maps from USGS.
But it is not clear whether the quoted paragraph refers to paper or
electronic maps.
