Building a Deck

My dad is a carpenter. He has so much knowledge about how to build and repair structures. My mom and dad came to visit from their hometown in Entiat, Wa- where I grew up. This weekend my dad and I helped my oldest brother Geoffrey build a deck in his backyard. I learned about the importance of measurement and estimation. We had to measure each piece of wood to fit exactly in the right place. Sometimes we would miss the measurement by the slightest amount and the board wouldn't fit. Also, my brother had to estimate exactly how much wood he would need to build the deck. After counting he thought he may have purchased a few too many, so he is going to have some extras. I suppose that is better than not buying enough.
