Wow! Twenty years of great reading in Plumbing & Mechanical.
Happy Birthday, PM! It has been a great run for a magazine. Since the beginning, I've looked forward to receiving my copy of the magazine that has kept me informed for all these years.
I started thinking about all of the changes that have taken place in the past 20 years. When you look at changes on a regular basis, it doesn't seem like much has happened. But, when you look at a period of 20 years, you start to marvel at the progress we have made.
