Free: Contests & Raffles.
Use what you’re most proficient with. I’d say the 270. After u get some bucks under your belt try a different weapon. As far as clear cuts, I find a nice stump, or pack a chair, and just sit where I have the biggest vantage point. Sitting for long as possible is all about comfort. Bring a pad or nice chair. Enough clothing, puffy jacket, snacks. I play cribbage on my phone a bit. Sure I look down and it passes the time, but it keeps me there hours upon hours longer. Take a nap even. If you’re too bored or frustrated you end up back at camp or home.
