Hire a guide for your draw hunt because they will know the area 1,000,000x better than you.
>but this all costs a lot of moneyHunting isn't a hobby, it's a lifestyle. Also, CA hunting is hard due to high hunting pressure, very low opportunity (wildlife mismanagement by CFW, and lack of access to public land for hunting. If you get serious, you will most likely need to go out of state, which costs even more time and money. Good luck.
