My whip crackin' worked. Around dusk last evening, the husband went out to cut the pipe. Had to wait for the temp to go down some. I was the fire watcher. Stood at attention, with my water hose and bucket. I was ready but luckily, no fires. But the sparks were a flying. I made the husband cut a little longer than he wanted. I had to get some pictures. He finally told me it was too dark and he couldn't see his chalk lines. Well, I guess that's important.
