Working in the field
Most people dont realize what it takes in order to build a house. There has to be tons of different trades at the site the has is being built at. But see I do something that most people will always need because I'm an HV/AC technician. Which means I work with heating and cooling inside buildings. For example right now I'm currently working in a house that is located in Aspen Colorado. At this house I apply and evaluate duct that runs through out the house. In order to do so I need to be able to understand and analyze blue prints in order to hang the duct in correct place. So my sheet metal work isn't in the way of plumbers, electricians, framers, or carpenters
