Anyone else doing this?
I started as a result of a thread on Mumsnet. It gets us out of the house and the SmallDragons walking with a purpose - we wouldn't go out for walks otherwise really but the lure of a "treasure hunt" drags my reluctant exercisers away from their DS Lites.
having said that, I've been stuck at my PC all morning trying to solve 7 puzzles in order to sort out a walk for next time I am being particuarly dense as I can't make head nor tail of any of the 7 puzzles!
