This is what I say to my geokid too ? he gets an initial rush of excitement and interest which waned quickly after 20+ minutes digging in bushes today! In our first cache we found a car left by Land Rover during a mountaineering event in the Lakes, he tells people that it came from a "treasure box!"
Thanks all for the advice and thoughts on this, I am struggling to find anything larger than micro round here (which is a pain as I have A fairly big TB to drop from the Lakes) which probably doesn't help. Mr Beat found a nano cache whilst we were away so might need his keen eyes!
IceColdUK, we're near Hampton Court Palace - suggestions greatly received! ?
