Sir,
If I can offer advice.
Cubs is a circus... a wild ride with kids bursting with enthusiasm. If you cant make a den meeting one of the other parents can and should step up and handle things. When you get back they should be able to tell you what was completed or not. What level are you helping with ? I have done Lions which was a crazy adventure with some very excited kindergartners.
Boy Scouts needs to be Scout lead and as an Adult leader why are you tracking what requirements are completed and which ones are not? It would help the troop and the Scouts, if the parents have questions about advancement to ask the scouts in question. If that fails then they can ask the scoutmaster to pass the info on to the PLC.
and Welcome to the Forums.
