Maryland: Consistent weather, occasionally but rarely humid, typically cool in the summer months, and rather cold during the winter (Not even half as bad as Minnesota though). Maryland's pride and joy is the Chesapeake Bay, and every public student will tell you that erosion from northern states and cities (ie New York) gets in the bay all the time. It's something that's drilled into your head from day one. Maryland is one of the most expensive states to live in. It has many company headquarters situated there, such as Discovery Communications and Geico. In the urban areas roads are typically neat and orderly, and are repaired asap.
It's densely populated, very urbanized, and very diverse. The state makes sure to have as many trees around as possible, and it really helps to give the area some color. In school you'll find a mixture of all races, and if one is dominant (rarely) it's not by much. In the part that I lived in, there's a heavy stigma against drugs and smoking. Sure kids'll joke about it, but actually doing it isn't very popular, and that's very reinforced by adults. The education in Maryland has been the top in the country for the past six years, and it wasn't until this year that the state dropped from #1 to #3, behind Massachusetts and New Jersey (Oh the shame!).
Rush hours (around 6am and 4pm) are hell, so leave early, or wait it out. Either way you'll get stuck in traffic. There are lots of joggers in the early morning, and the lights of a waking city are always beautiful to watch. People mostly keep to themselves, and it may seem to new arrivals that people give you a constant cold shoulder. When you talk to someone, they'll be surprised, but they'll typically reply politely and might even continue a conversation with you!
Overall, it's a very good place to live (if you've got the money).
