mmm. think we might be getting hooked on this. we passed 4 geocaching points on our thames walk yesterday. we found two and failed on another two. the problem of doing them in the middle of a 7ish mile walk is that you can't stop for an hour and do a thorough search. but it helped break the walk up and was all good fun.

here is esther with one of the caches.

and here is a bridge where we didn't find one.
