Everyone can find somebody to practice small talk with. The benefit of conversation practice isn't contingent upon doing so in quick succession, but accumulation of conversation experience over time. You can increase your skills very rapidly even without access to the condensed conversational environment of fraternity/sorority recruitment. I don't even recommend participating in that if you can avoid it, since it's a very stressful experience. But it does make you really good at talking to people.

Go to a bar, people are usually there to talk. Interestingness varies considerably, of course. If you work, make small talk with your coworkers. If you're in school, say hello to the person sitting next to you. Make a habit of doing this wherever you go. That's the best way to practice.
