My two WIP towns are in my signature, but my first town as well as my wild world and city folk towns were all named 'Ivy City' That name is really sentimental because i have had it for so long
My town's name is Houdini. I wanted to sit down and think up a better, original, and whimsical name, but ultimately ended up wanting to take it casually... So I chose a name pretty much at random (also why I ended up with the name Ploopa for my mayor).
My towns are Lullbury and Avium. I chose Lullbury like three years ago, so I don't really know why I chose it. I like it though. As for Avium, it's a Latin word I liked and appreciated the meaning.
