Don't start. You'll go broke. Price of fur vs cost of gas isn't worth it......

Seriously, try to find someone with experience that you can tag along with. The local fur buyer or trapper associations would be a good place to start. Connibears at lodges and bank dens are effective if legal. Setting dens isn't in a lot of states. Nothing like pulling up a set with a nice beaver. Makes you think you're jeremiah Johnson.
