I'm more of a jack of all trades sort, but compared to most people I know a lot about traditional construction methods. That said, in some of the circles I mix in, my knowledge is not that extensive by comparison, so I don't feel that knowledgeable until I talk to someone not in that world then I feel like a guru, but that doesn't come up too often unfortunately for me. 🤣
