Well I have found some pretty strange thing in caches,most I will not list and got rid of it.
I always update it with something better.
I will mention the Geocaching panties though,at the time I did not think about it and it was not in the rules but these were ..............well and had a geocaching logo on them too.
as far as utilty tools if appropriate and in the appropriate cache I would welcome them.I do not have a problem except in urban setting,but the Rural country,has it's place the country and coutry kids all have them.
