I finally got the chace to come up for air. It's snowing here in Pittsburgh. The rooftops are slippery as are the roofs. So I'm here in front of my laptop. After doing this work since the early 70; I don't need practice. I've slid on enough roofs. The changes I've seen in our trade could fill a book. Much the same as many of you out there. But this trade has always paid the freight and we've always helped each other. Keep it up!
