Greetigns all and potential GeoCachers.
I stumbled on this site, rather by accident today. I was searching on the specs of a GPS software update on my Magellan Companion GPS unit that I purchased recently, and I'd like to take a moment to speak on a couple things regarding GeoCaching.
Though I'm a NooB in terms of this community, I'm familiar with this concept, and it can be a very rewarding pastime, or something to wast a Sunday afternoon if you've got nothing better to do...however, GPS ownership isn't necessarily a requirement. Though it DOES help, and make things easier, you can also do it "the Hard Way", and use a map, (topographic or otherwise), which can also prove quite rewarding.
Having or not having a GPS can make this a fun hobby either way. You can look up the coordinates, or do it the old fashioned way, and plan ahead.
One thing to mention about using a map. If you've got an old set of topographic maps, chances are you'll have to look/work harder. Reason?....the older maps can (and often are) off by several degrees due usually to human error, but it can still be a fun and rewarding pastime, all the same.
