Geo- caching

One of my team-mates on UKS posted me to a link about this latest craze. Hardly daring to check it out , given my adictive nature, I immediately logged on and found that there are nearly 5000 caches or treasure sites within a 50 mile radius of me . Early days , but I think the idea is that you trek off into the great outdoors with a sat nav thingy in your hand and put in the co-ordinates that you've found online . It usually comes with a quiz type clue that you have to decipher to pinpoint the exact location. Once you've found it you open up the container, sign in to say you've visited and take a little reasure token or sime such and replace it with one of your own. It's all I can do to wait for the boys to come home from school before dragging them off to locate it ! I'd never heard of it before this morning but it sounds like great , wholesome, family entertainment that uses technology ( which the boys love) but which doesn't involve them sitiing in front a screen for hours ( which I loathe) ...so everyone's happy ! Thanks Elaine !
