I kid you Vince, but if you are going to use wood for a deck, while pine is the cheapest, it doesn't last long. Composites like TREX or its competitors will last much much longer. It is a bigger up front expense but since you are planning to stay there a long time, the cost will be negated. I know for some looking at the initial investment and how cheap pine is to composite seems the better value, but a guy like you, that looks at the big picture, certainly you can see the value of staying away from pine which rots and warps at a faster pace than almost any other wood.
