Diferent strokes for diferent folks. At age 53 I took up scuba diving. Wanted to do it for 30 years. Finally did it. Waaay cooool. Even diving the diry lakes here in MN is OK. Going to Key Largo in Feb. I like the idea of making a crossbow. I do some woodworking myself ( not enough to call it a hobby). Do you have any plans for the crossbow? I would like to build one. Note-- If you have something you want to try don't wait till you are 53. Find some way to do it now. It's really too bad that a lot of hobbies are expensive. My motto--- If you can afford it -- do it. But remember --- Family first. Maybe that's why I didn't take up scuba diving till age 53
