Clubbing

My golf bag wants and vision don't match the game I play. I play a 9 hole par 3 course 99% (70 rounds a year) of the time and big-boy golf or scrambles (5 times a year). Why do I feel the need to have a driver, two fairway woods, two hybrids, irons, 4 wedges, and a putter? Just how far into the wilds do I go and how precise is my game from the edge? Roughing it in the motel 6 version of my golf bag I could play with 8 clubs and maybe even only 5 or 6 clubs. It isn't a matter of weight as I use a pull cart. I found my bag wanting for an adjustable driver and another Mashie hybird.
