What's that? You've never heard of caching? For shame! In all seriousness, we're surmising that quite a few of you out there may have overlooked this up-and-coming jewel of recreation, but Garmin's doing its darnedest to change that. The GPS maker has just opened up a new online community at OpenCaching.com, hailed "a completely free online community for creating, sharing and finding geocaches around the world." For those out of the loop, caching is akin to a sophisticated game of hide-and-seek, where individuals download GPX files and then head out on adventures that'll lead them to various surprises and / or treasures.
