Here is a little background, back in July I took a friends teenaged son out with me so he could learn a little bit about using his GPS and geocaching. Since that time he has muggled 2 TB's that I dropped that evening and continued to return to one of the caches whenever they would go to the lake swimming. His father found out and managed to return the TB's to me. I logged them as a grab and will drop them far away from the teen. I also informed the owners of the four caches we went to, to possibly offset them from the original coords.
As of now he doesn't have an account with geocaching.com so I think the caches will be safe if moved a 100 feet in any direction. No coords no cache.
Did I handle this correctly and is there anything more I should try to do?
