Towns there include Bethesda and Potomac. The west and north are full of farms and small,quaint communities like Poolesville, Barnesville, and Damascus. The center contains the large cities of Rockville and Gaithersburg, the county's government and financial centers.

Suburban county of Maryland

One of the few counties where there's a ghetto area (Wheaton, Silver Spring), there's a rich-ass area (Bethesda, Potomac), and the boonies (Damascus, Poolesville) all crammed together.
That's diversity for you.

One of the richest counties in America. To sound cool, we say we're from D.C. but really, everyone can tell we're MoCo at heart.
Person A: Where are you from?
Person B: Washington, D.C.
A: But you have a Louis Vuitton bag and drive a BMW.
B: I'm from Georgetown.
A: Liar! You're from Potomac aren't you?

1) Montgomery County, Maryland. In it;s location right next to DC, it has DC's violence in some parts, while it also has the richness of Orange County California.

2) Home to many of the 2002 sniper shootings.

MoCo is only used for Montgomery County Maryland. If you use it to define some other Montgomery County, I will personally jump you.
Let's all visit MoCo for some fun fun fun!

The county where everyone is either straight out of the OC or tryin to be ghetto. But the love is all in MoCo. And whoever thinks that we stole the MoCo from Howard County, it should be pointed out that Howard County is HoCo. And yes, their girls are hos.
Girl from MoCo: Yeah, I got into every college I applied to!
Guy from PG County: What is college?

excellently defined above, but with one vital part omitted---a super-liberal hippie village in the mix (Takoma Park).
MoCo is extremely diverse and awesome.
