A lot of us do Woody but finding a walk out of your area is quite difficult , you can drive straight past a walk in the blink of a eye and miss a cracker .
That Geocaching looks interesting. I got Viewranger GPS for my phone then never used it as it was battery heavy (and it always seemed to be raining and I need a waterproof cover)... Geocaching adds another dimension doesn't it.
^ We recently started doing the Geocaching with the kids locally, after being introduced to it during the xmas holidays, its great fun, makes you think a bit too!
