Recently discovered that there has been a merit badge for geocaching since roughly 2010.
I believe Waymarking has a lot to offer and requires a different skill set regarding use of the G{S, a digital camera, the research and the write up. Waymarking does feature Eagle Scout projects. Most kids now have access to computers. I stumbled over learning to upload images in a timely way. Sometimes it does take a team.
One to hold the GPS, one to make notes, and another to do the images.
