Let’s say, for the sake of argument, that you want to impress the woman you’re seeing. I know, crazy idea, right? But c’mon, men. It’s going to take more than just dinner.

And look, I’m a fan of dinner. A juicy steak, a glass of whiskey, a great restaurant—that rocks. But any guy can do that. Presumably, you like this woman, so you want to stand out from the crowd.

Here’s a surefire way: geocaching.

It’s not just for the kids. If you aren’t familiar with geocaching, it’s basically going on a scavenger hunt around the city, tracking down little caches of buried treasure with a GPS app, and then celebrating when you find them. Simple, right?

It’s also a fantastic way to get to know someone. My personal recommendation? You’ll need to stock up in advance with a few knick knacks—maybe a snow globe, a matchbox car, a key chain. If you take something from a cache, you need to replace it. Otherwise, you’re a douche. And you don’t want her, me, or the lamppost to think you’re a douche, do ya?

Here’s what you need to know.

Maybe she had a crummy week. Perhaps something didn’t quite go her way. Traipsing around the city hunting for treasure is a much better way to get her mind off the shit that didn’t work out than dinner is. Searching for a little pouch of treasure tucked away on a shelf in the New York Public Library is guaranteed to improve her mood. Plus, there’s just something about libraries. They’re catnip for most women. When she finds the red drawstring bag tucked behind Jane Eyre with a miniature book inside it, she might even give you a kiss. And that’s one more thing to help her out of her funk. If she keeps the miniature book, replace it with a snow globe. A snow globe will get the next man who finds it a kiss, too. Pass it on, bros. Pass it on.

Maybe she’s got a thing for the Brooklyn Bridge. Include a cache on the bridge on your hunt. When she tells you the story of how her mother took her and her brother to this bridge to watch the sunset when she was younger, you listen. If she shares a story of how those walks remind her of someone she lost long ago, you pay attention. Look in her eyes, tuck her hair behind her ear, and let her know you care.

Include a geocache in Grand Central. (There are hundreds. Look them up.) Track one down and replace the Lego dude you discover inside it with, say, a small model train or a matchbox car. But you’re not done. This is a two-part cache, and the second part is a surefire winner.

Head to the Whispering Arch Gallery on the lower floor of the terminal. It’s near the Oyster Bar, between the intersection of two walkways. If you press your ear up against the tiles, you can hear someone whispering from the diagonal arch. This acoustic anomaly is a chance to tell her something that you’ve been keeping secret, holding back, or just weren’t quite ready to say before. Maybe you’ll say do you want to go out again, or maybe you’ll tell her how you feel about her. Or maybe you’ll admit there’s a part of you that’s glad things worked out the way they did so you can spend more time with her. She might even whisper back her own sweet nothing that can be heard crystal clear over the din of crowds, but only by you. She might even say Me, too.

Wander through Central Park searching out a cache hidden behind the Alice in Wonderland statue, as kids clamber all over it and she watches them with a smile and a wish in her eyes. When she asks your favorite memory from when you were a kid, tell her it was the hours you spent in the park with your brother and sister, pretending you were pirates and hunting for treasure, too. Tell her you loved that it was always your job to make sure everyone made it home safely. But, dudes, that’s my fucking story. Tell your own.

Some geocaches will bedevil you. No matter how hard you try to find that one that some website said was absolutely in the 72nd Street subway station or definitely in the lobby of Radio City Music Hall, you’ll never track it down.

Remember, you’re in this together with your woman, and if you don’t find one, try to have the best time possible. Tell her you’ll do it again the next month. There’s something about those words—try, try again—that might be exactly what she needs to hear.

When she thanks you at the end of the date, you can thank me for being your guide. Because she just might be into you.
