considerations...
We lived in the area recently, and used to go for walks in Sheffield. I liked it pretty well, until one day we saw some youths stop a car in the middle of the road, get out, and stare at the pavement where someone had whitewashed over some graffiti (so that it couldn't be read). Made me start to wonder what was going on there.
It's obvious that people take pride in the neighborhood, and we ran into plenty of friendly people. The houses are pretty close, so if you value privacy you may want to consider that. There also is a lot of construction at the Billingsley side of the circle, and traffic on that road is noisy with all the constant dump trucks, etc. With the growth plans for the area and the landfill, I believe that is NEVER going to go away.
We decided not to consider a house in the area because of the crime trends in Waldorf neighborhoods.
