Visiting a town!!!!

Hey everyone! I recently started replaying new leaf and I'm looking for some towns to visit. I don't know anyone else who plays the game. I want to experience this aspect of the game. I feel like I'm missing out on some fun stuff!

Does anyone want to be nice and be my ac friend?

I'm little nervous about posting my code online. Has anyone had a bad experience when trading friend codes and having visitors? Like someone ruining your town?

Thanks!
