Everybody has a different idea about the goals for your travel bugs. In my feeble brain The choices are lots of caches, quality caches or lots of miles.
I know there are a few others that I am not thinking about. I handled one recently that a navy family released in New York. It was called Surfing to Hawaii. The tag stated the were being stationed in Hawaii and wanted the bug to join them.
But my question is what is Your main desire/goal for the majority of your T/Bs.
