I hear ya friend-I've found the best cribs are made from 8" splits in half, they settle nicer----and set up real solid---mine really arent moveable, as you stack in between just strategically place weight from the interior splits over top of the crib splits like every 12-18" or so---it stabilizes and keeps the crib stack from moving to or fro...Good Lord this addiction...
I'll quit making excuses and get that 5th bay empty before next season---it now holds kindling, my sharpening desk, archery target and fire pit burner that I keep out of the weather when not in use...handy for those things, but thats aerified space for another cord of wood...shame on me...
