Oh, it's not just coin ops. The phone rings here constantly - greenhouses, dairy operations, etc. Now that some other stuff is in the works the boiler work is going berserk. The really cool part? As computer network guy the flows, exchangers, heat levels, etc, are all things easy for me to grasp. I can't do it yet, but I think in a month or two I could learn the design portion of Chuck's trade well enough to toddle off on my own and guide a crew of unemployed plumbers in duplicating this. That's the plan here ... a plumber with a crew of four had to lay everyone off a few days back ... and we'll put them back to work :-)
