I got an old chlorine bucket with a screw on lid from the pool guy and drilled a few holes around the rim...it's rain proof but still breathes. BTW, I cleaned the chlorine out very good...
I store seasoned dried wood in a 55 gallon drum with a clamp banded lid. I was going to use the drum for a second UDS, but changed my mind. The trouble and time spent removing the phenolic lining wasn't worth it to me. I have also been known to use one of these for the smaller chunks:

Good luck,
Breath-ability is key. For the Lang it is a wood pile on skids and under a loose fitting tarp. For the charcoal cookers, the chunks live in milk crates on a shelf. Out of the weather of course.
OK, I'm spoiled but I buy kiln dried hickory from a local suplier and store it on a pallet in my pole barn along with my round roles of cow hay. Great wood, plenty of circulation, no rain.
I take cardboard boxes from work that are gonna be thrown out and use them. Just cut a few holes in the side and leave the top open. I fill them and then store in a ventilated but dry place. For me, that's the backyard shed. It isn't air tight and breathes well but keeps the rain out.
