I don't worry about separating it much as I'll just grab what I need as I need it. Tonight I ran out and grabbed an armful of small rounds, nothing over 3", they work great to fill in the top of the larger splits and they burn hot. By the time I shut my stove down after refilling it the top inside was glowing a bit, the temp gauge wasn't even up to 500 yet.
Not a good time, but because of that many places have noone in there getting anything done. Who knows, maybe you can get in in the next 4-6 weeks and be back up and running before spring. If you need a hand cutting and splitting I'd be happy to get some guys together and help, but you'll need to get the kids to stack
