Well?
For me, its Massachusetts. I like this state a lot. If you actually go exploring, you can find a lot of history and great architecture around. In fact, in my town, theres a huge fort where the revolutionary war took place. And the Town center is filled with a whole bunch of hige buildings built in the 1800s. There's also a bunch to do here like going to sports games and whatnot. We even have a Six Flags where people fall off the Superman roller coaster..... okay maybe that only happened one time... But anyway its great and you should come here.
