Thanks for all the input, that makes a lot of sense to see Webelos I/II as one curriculum. I'm working off a book and den leader guide I purchased last year (2017), and it has geocaching, but this is an outdated copy already? That's a bit irritating, now I have to go back and make sure our curriculum last year was met.
We are trying to finish up our requirements for Webelos II to get our Arrow of Light. Some of the requirements we've done before - we've gone geocaching several times, for example. Is the expectation that we should do that requirement that year? I'm sure the boys would love to go geocaching again, but if anyone misses that meeting, can I go ahead and give them credit for when we did it last year? Thanks for the help!
