Thanks for the info! Macnuts are one of my favorite things, and out here as you can imagine, I get lots. While we were in Hawaii we went to a couple of small macnut farms - saw some waaaay cooool old husking, drying and cracking machines. Then we went to Mauna Loa, and I was touristing it up. Had lots of fun! Did you know it takes 300lbs per square inch of pressure to crack em??? They used to do it by covering the nuts with boards and running a truck over them!
