This activity was amazing! One young woman's mother told me her daughter, who's usually not very vocal about our activities, couldn't stop talking about it when she returned home that night. To me, that was success!

What we did:
1. They (the Young Men's organization was in charge) gathered random information (description, likes, where serving, etc.) about the current and recently returned missionaries in our ward.
2. They had men from the ward who went to those missions or parents of the missionaries prepare and bring a food item to share with the youth.
3. They had each "mission" set up in a different room throughout the building, and had the youth rotate between the rooms to not only learn a little about that country and eat their food but also guess which ward missionary was currently serving in that country.
4. The Young Men began the evening by quoting Section 4 from the Doctrine and Covenants.

If you try this activity, let me know how it went. I'd love to hear about it.
