DarkFlare: Well after some soul searching I have decided to end the life of this cache. it's not the first time it's been muggled and I fear it wont be the last as i discovered it seems to be a party zone in the summer months ( very odd considering a river runs through it) I just don't want to keep spending money on getting this interesting container and big heavy duty magnets.
Sorry to all who left without a find. RIP swimming upstream.
