I have been a professional trapper for going on 36 years now. I manly do wildlife control and fur trap in the winter. way back when I was a young pup, I wanted to be a long liner, that is a rough one to do in these days and times, but can be done if a person has enough drive and health to them. but that person will need summertime work as you already stated. I chose to do the ADC and have never looked back, I am home with the wife most of the time unless I am doing a talk somewhere. My kids are grown and I get to see my grand kids, as a fur trapper you will need to be moving along to new ground so travel will be a must. as far as trapping I have traps out 365 days a year unless I go on vac or out of state for a seminar or do a in house training. I also make and sell baits and lures, deer scents fishing scent and game calls. You will need as you stated another form of work in the off season. and I can tell you when you trap for a living it is not all fun and games, and that is really true if you have a family to provide for. I would not trade doing what I am doing but sometimes, just like any other job it can get old and burn out can come. make your plans based on your know how, what you need to live on, and where and what you want to do and achieve. just some thoughts
