Thanks for the suggestions so far.
SSScouter,
"One is not to add to or subtract from the requirements." This is really why I posted the question in the first place. We have our own Day Camp planned and a full day's worth of activities. Our reservation is at a Scout camp (but there will be no "SCOUT CAMP", the event, in progress while we are there).
It's also about a 40 minute drive, so I'm considering that this may fulfill that requirement. ?
Somewhat unrelated poll, but I'd love people's input: suppose you took your Webelos Den and their parents (who helped their boy pitch the tent) to camp overnight at a scout camp with a troop. Would you pass off both 4 *AND* 12?
"4. With your parent or guardian, camp overnight with a Boy Scout troop. Sleep in a tent that you have helped pitch."
"12. Visit a nearby Boy Scout camp with your Webelos den"
