Laura (no name) has done it. She has found at least 10,000 caches. She doesn't log them all, but it is about the hunt and spending time with friends for her. She introduced me to this sport/hobby back in 2008. We have traveled all over the country, to Canada, and Ireland together grabbing caches and spending quality time with each other and the geodogs. She makes it more enjoyable for me and I appreciate her companionship. So, lets give it up to the Warrior Woman and her nice milestone.
First cache find: Hualapai Windmill on 19AUG2007. Ten thousandth cache find: Spring Ditch Clean Up 2017 on 30APR2017.
