I just finished a table to go with my Egg (it does not actually hold the Egg so I didn't post a picture here) and was wondering about keep the lump outside in NC. The table should be waterproof (but just in case I plan on covering it with a tarp when not in use) but I was more concerned about humidity. Does anyone else store their lump (and other chunks of wood) outside? If so, what do you keep them in? Just keep them in the bag or some other container?
