There are a few things to keep in mind. One is that this is not a merit badge. Another thing to consider is that any youth from any youth organization, (BSA, GSUSA, etc.) can earn this. GSUSA Councils can have their own Caving IPP. BSA does have the Caving Elective for the Ranger Award.
This maybe something that different summer camps can fashion a caving program around.
I think the "bat sticker" is still a NSS membership only logo. We should come up with something new, unless part of this will be to join the NSS
Start brain storming....
