Thanks to all for the good words... as I indicated in the cache log the find was kind of ironic...
When we started Sunday we had only a plan for route of travel, not number of caches, milestones or otherwise... It wasn't until I was logging our finds when I realized we hit Hollora's tribute cache for 500... and that wouldn't have been the case if we had found all of the caches we stopped at leading up to it.
Oh and for all that know mom.... She stayed up right all day long
Thanks again... and many thanks to Eki for this series!!!
