Well yesterday I got a mini score of Acacia that someone had cut down from their yard. There was about 5-6 pieces about 12-14 diameter and 4 crotches and a few other smaller pieces I grabbed. It was cut over the weekend and already had some mild end checks. When I got home I piled it up on the tailgate of my truck and started sealing. As I was painting the ends I could HEAR it crack a few times. So yeah wood splits pretty quick down hear in AZ. I thought it was strange that I was hearing it though, I guess it doesn't help that it was in the upper 90's yesterday.
