Years ago (five, maybe more?) I went to a session at either Dynamic Landscapes or Vermont Fest on geocaching in the classroom.  It was focused on using little tags that went into a geocache and then got picked up by other people, and students could track where they went all over the world (I'm pretty sure they were Travel Bugs, but might have been something else).  I've looked through all my notes and can't find the name of the person who did that presentation.  Anyone know?

I'm asking because I'm looking for someone to lead a session on basic geocaching in the NEK this June.  I was thinking of this person who I saw years ago, because I remember her being very engaging and dynamic, but if I can't figure out who that was, or if she's no longer in the area, anyone know of someone else who might lead a session?  

Thanks!
