I saw this video and it's something we can do within Noobstown. It doesn't require any special mods, just an understanding on how to find your coordinates and some cooperation with the land owners in the Wilderness.

The way I see it, is that we would have a "geocache office" where Wilderness property owners can place a geocache on their property such that it would be accessible to anyone wandering the wilderness areas. Each participant would add an entry to a Geocache book with their X, Y, and Z coords of a geocache at the G-Office, perhaps at the Wilderness Tutorial site. Those who want to seek out these caches, would pick one and head out into the wilderness. Yes, you can make use of the /visit feature to take a shortcut, but real cachers walk the whole way.

Property owners would be encouraged to provide shelters for travelers as they trek through the wilderness, in search of the caches. When you find the cache, you can sign it, and you are encouraged to leave a trinket of some sort in the cache and take a trinket someone else had previously left there.

What do you think of that sirs?

Yeah, this would be nice, I'd love to see this in the game.

This is a really cool idea! Sometimes on trips when I have nothing to do I go geocaching. It would be nice to do it more often, especially on Noobscraft where possibilities are (nearly) limitless! *Stamp* APPROVED
