“You have to be odd to be number one” — First of each geocache type

“You have to be odd to be number one”
— Dr. Seuss

The first to be something, now that’s something. Although a few of these geocaches are open for a spirited discussion, we’re fairly confident these are the “firsts” for each geocache type. Keep in mind that in the early days of geocaching, it was easier to change cache types after publication. Nevertheless, these geocaches should be fairly “pure”. Check out our list:

First Virtual Cache

Rift Valley
GC53
6/15/2000 (The user carved his initials in a tree, years prior and listed it as a virtual cache in September of 2000, backdating to June of 2000. It’s possible that “Virtual Dublin” GC60 may be the true first.)

First Letterbox Hybrid

Open Space 6
GC190
