Ya know, it wouldn't surprise me if we have met at some petro-chem job site sometime. Are you a piper (that is not a pun)?
No, I work on commercial mechanical systems. I was a toolbag guy for years but I design control software and commission systems. The last few years I have worked on new/remodel system design with mechanical consultants (engineers) that work for us.
All of my work has been in the Denver metro (you know, MileHi) area.
I've done some pipe fitting, I like my laptop a lot better. {:0)
