My Dad and Uncle had a plumbing and heating business. When I was a kid, I thought all the tools and fittings were pretty cool. He passed away before I was old enough to work there. The business got sold/given to my uncles kids who had little or no work ethic, and was disolved shortly afterwards. My son wanted to be an HVAC tech but I talked him into being an electrician. He's taking his apprenticeship aptitude test on Tuesday!
