Just trap during the weekend. Remember, you are representing all the trappers in the U.S., if you do wrong everyone will tell the world. Just like the old business saying, if you give a customer good service he tells a few friends, if you give him bad service he tells the world. The same goes for trapping. I hope you have learned enough so far, that you feel confident enough to get out there and trap some fur.
Trapping is a wonderful sport, hobby, or full time job.
Become one of the elites of the outdoors and learn to trap every animal in your area. Have fun and good luck.
