Having a mentor is a huge advantage, but not a deal breaker if you really want to hunt. Figuring out seasons and tags isn’t that hard if you have even modest reading comprehension skills. Every state in the nation has public land with game on it to hunt. Some is better than other. Figuring what’s good and what’s not is part of the process. Success is not and shouldn’t be guaranteed.
I think the biggest barrier is the hunting industry itself. They’re lining up to get their hands in your pocket by convincing you you need their products to be successful. That’s 100% bullshit. You don’t need name brand hunting clothing, a custom rifle , or thousand of dollars in camping great to become a very lethal hunter. A pawn shop rifle and the clothes you have in your closet are sufficient to learn with. If you want to learn to be a killer, buy a .22 or a shotgun and learn how to find, hunt, kill, clean, and cook squirrels, rabbits, or whatever small game is available within reasonable distance of where you live. Once you’re proficient with that move to bigger game. Kill the first legal animal you can. Crawl, walk, run. Again, it’s not supposed to be easy. Quit whining and get after it.
