since i worry about measuring, i used my iron to make a fold mark in the middle of each block, then i sliced at that point, which ends up being the middle of the block. rarely are two days the same for a pilot. the hours are 7 until 10 a.m. and of course it's open to the public! reliable, high quality lights and video handling equipment make the difference in their daily operations. however, i think i am going to tinker around and see about baking them in a loaf pan and then cutting them across to form "bars".
