The Minneapolis Streetpass community is meeting at the Mall of America. These are pretty casual meetups. Aside from Streetpassing, this is usually a good opportunity to play 3DS multiplayer games like Mario Kart 7.
We will be meeting outside of the 3rd floor Gamestop. It's next to the North food court and the mini golf course. We'll just be sitting around at the tables there.
Since a new puzzle for Brain Age just got sent out over Spotpass, this should be the perfect time!
