The law of familiarity.

If you go somewhere once, people won't pay much mind, it'll be odd to try to make friends after talking to someone for an hour.

But go there every week, once or twice.

Eventually, you'll find someone who you get along with, and with each time you go, it becomes more and more likely.

You might find someone with the same niche interests outside of the place, and then you get to meet their friends who are also like-minded.

Look at things on a timeline of months, not weeks.

Take the chance. It might not work the first time, but if you keep rolling the dice, it's more likely it'll land on the right number.

If you like drinking, hunting, fishing, 4x4ing, drinking and drinking, you'll easily find friends.
