Mafia Challenge: D5 T5 Diversity Mystery Cache

This cache has been archived.

Memfis Mafia: After a lot of thought, I’m archiving Mafia Challenge: D5 T5 Diversity.

This one has been a strange little paradox from the beginning—in the best way. The physical cache is intentionally simple: a tiny nano on a park bench, an easy stop, quick signing spot, low barrier to access. But the challenge attached to it? That was never meant to be simple. This was designed to be a long-game accomplishment—one of those “game within the game” milestones that pushes people to stretch their experience, broaden their caching life, and go chase stories instead of just smileys.

And it worked.

Since it was published back in November 2017, this cache has become more than a container. It’s been a checkpoint for road trips, a motivation spark for people who realized they were “one type short,” a reason to chase that fifth state, a catalyst for those wild D5/T5 adventures that don’t happen unless you decide you’re willing to commit. I’ve read so many logs and notes from people signing early, qualifying later, coming back to claim it, and celebrating the moment when their checker finally turns green. That arc is exactly what challenge caches are supposed to create.

But here’s the reality: I’m long gone from this area—about 1,500 miles away—and I can’t maintain this cache the way a cache like this deserves. Even though the container itself is small and straightforward, challenge caches tend to attract steady traffic, a lot of “sign now / qualify later” visits, and occasionally the kind of attention that makes a nano on a public bench… well… a nano on a public bench. If it goes missing, gets damaged, or needs attention, I’m not around to handle it quickly—and I don’t want to put that responsibility on local cachers who didn’t sign up to be my maintenance crew.

There’s another part to this decision, too: space matters. This cache is in a location where local cachers could place their own challenge and keep it actively supported by someone who’s actually here. Geocaching communities thrive when hides are owned and cared for by people who can respond, adjust, improve, and keep things healthy. Archiving this listing is my way of making room for the next person’s idea—someone who can keep it alive without the “owner is half a continent away” problem.

To everyone who found it, qualified for it, wrote notes, posted your checkers, or used it as a long-term goal: thank you. You’re the reason this cache mattered. Your stories—about boats, climbs, puzzles, travel, weird gear, late nights, and that one last missing icon—are the real logbook. The nano was just the pen stroke at the end.

And to the folks who came through the area, signed the log, and left a note saying, “Not yet… but someday,” I hope you do get there. That’s the heart of this cache: not the bench, not the nano, but the ambition. The quiet decision to level up.

Finally, thank you to the reviewer and the local community that keeps the framework of this game standing. Challenge caches are a niche inside a niche, and the fact that they can exist at all is because people care about the long-term integrity of the game.

As for me—this may not be the end of the idea. There’s a decent chance I’ll build something similar again in my new home state of Florida, where I can maintain it properly and keep the challenge spirit alive without leaving an unattended listing behind me.

For now, though: it’s time to close this chapter with gratitude.

Thanks for playing the game within the game—and for making this one worth having.

📍 About the Physical Cache

This one is simple. While the challenge is a beast, the container itself is not. The cache is a nano, camouflaged to match the bench it’s attached to. The terrain rating is a soft 1, though those with limited mobility may find the low reach a bit tricky.
