Up here in Alberta many people take a quick course and then write a test. I received mine by going straight to work for an outfitter as a kind of apprentice. I would call or go to your nearest Fish and Wildlife office and ask them. I think it's a fairly simple process anywhere.
As I sit and glass, which is common for hunters out west, I have sort of quickly discovered something I never learned when I was younger.

Carry your soft spot with you!
