Try going to the mall, your school (if your friends have it), to a bus, in a city, in a train, or anywhere you can find lots of people (like a parade show).

You can also go to Target, Best Buy, or GameStop to see if you get a Streetpass from a demo 3DS.

Some Gamestops have certain days dedicated to streetpass. Check their website.

You should go to a crowded place like a city or a big nintendo event.

If you ever go to any games/anime conventions (or similar events) you can potentially get a couple of hundred pretty quickly.

Just remember that you have to keep visiting the plaza though, since you can only get 10 streetpasses at a time (then presumably the 3DS stops streetpassing till you make room again).

Game conventions, crowded stores / malls, movie theaters (first showings of popular movies), gamestop, and crowded city streets are all good places to get streetpasses. Also try college / other school campus if there is one by you.

Since you're in Florida, you may want to try the airport, amusement parks, shopping malls, and possibly beaches along with the normal places (college campuses, downtown areas, game stores, etc.).

The second day I had the 3DS we went to a Japanese festival and got lots of streetpasses. Try going to events like those (asian, taking pictures, game places, popular places).

Check out game stores, shopping centres/malls or gaming events. Sometimes people host streetpass events in areas so check out if there is any in florida.

I went to Walt Disney World this past summer and passed 57 people across my 4 days there, so make sure to bring if you ever go there.

School. Stores. Anywhere where there are many people.

Video gaming conventions often yield dozens or hundreds of StreetPasses at the right time.

Well, it depends on how popular it is where you live. Florida is a big state, so I'm surprised you have only StreetPassed 1 person, while I'm in NJ and have 63.

Bring your 3DS everywhere you can. I you go places with your family, popular places such as well-known zoos, amusement parks, even boardwalks will get you some StreetPasses! You never know when you'll get one, so, like I said, bring it anywhere you can.

Video game conventions, expos, ComicCons, popular malls, movie theatres, and concerts.
