Every time I went caching with coordinates straight off the page, I ended up about 1000 feet S of where I eventually found the cache. I then took waypoint readings at the actual cache, compared it to the given coordinates on geocaching.com, and then averaged the results. This was with my first ten caches or so. After that, I simply add this number to each location, and it puts me where I belong.
Again, if there is anyone else who has encountered this or a similar problem, please let me know.
