Vasectomy.
We had a three wheeled stroller (small bike size tires) we used on improved trails a lot. It had bicycle brakes on it so it was great. I like the trailer idmt had.
I didn't build one but I do have one I purchased. I like the WSMs I have both the 270 and the 300 and both have taken elk at approximately 400 yards. I have shot plates at 800 yards but I'm not good enough to do that on an animal in hunting conditions. I think there is still ammo available...
Grew up in Arkansas, lived in Kentucky for a few years, and now live in Oklahoma. Oklahoma is great if you don't mind really unpleasant weather for 120 days in the summer. Cost of living is good IMO and with your purported skill set, you can make a good living. Happy to answer any questions...
