# Reverse Geocache Box

## Overview

![](https://cdn-learn.adafruit.com/assets/assets/000/002/873/medium800/customer_projects_propose.jpg?1396788214)

Adafruit customer Kenton Harris used a reverse geocaching box to propose to his girlfriend (she said yes). &nbsp;After the project build and successful proposal, he shared how he built the reverse geocache with us. &nbsp;We thought others may be interested in building a similar box for their own proposals, or for fun!  
  
A reverse geocaching box works similar to other geocaching devices. &nbsp;It will guide you to certain coordinates on earth and instead of finding a geocache located at those coordinates, you carry the box with you, and it opens for you at a predetermined destination. &nbsp;This is also a&nbsp;great way to do a scavenger hunt (making someone go to multiple locations before the box opens).
