I use 3D Classics: Excitebike as a tech demo.

You'd be surprised at how effective it is.

I live in New York, so I have no problem finding Streetpasses...
My boyfriend and I each got ten Streetpasses today when we went out shopping...
The cool part is that even though we were together, we didn't get the same people...

I live in the Houston, TX area, depending on where you go, Streetpass connections are rare, outside of people you know that have the system or conventions and big movie weekends.

Most of my puzzle pieces I've gotten have been bought via the tokens and due to that randomness of it, I have more then a few puzzles that just have one or two pieces missing outside of having nothing in the special piece sections.

Still trying to beat Find Mii twice so I can get access to the sequel.

Ironically, everyone I come in contact with seem to have no less then triple my number of Miis in the plaza. If this works, the my plaza will finally be a more lively place and the puzzles less annoying.

If it involves my 3ds leaving my house, it won't help.
