RE: [gpsstash] Provide more than one GPS waypoint?
This sounds too complicated to me. Why not simply state the cache is X feet from the nearest trail?
The only way you get into bushwhack mode is you didn't consult a map prior to the hike. Part of the problem is it is "advertised" that all you need is a cheap (under $100) GPS to geocache, where in reality unless you are skilled in map reading, you probably need a GPS compatible CDROM map.
