After a few years of using gas, I have become a devotee of charcoal BBQ,
at least for steaks and a few other things. I love it. The one big
bother is storing the bags of charcoal.

My current thought is to store it in one of the large plastic outdoor
bins (with other BBQ odds and ends) you can buy at Home Depot and the
like. However, although water won't get in, the humidity will certainly
vary wildly. Will moisture absorption by the charcoal be a problem,
reducing its effectiveness? It would be store there summer and winter,
though our northern climate has very dry winters.

Thanks,
Paul
