    "Great place to raise a family. Safe and sheltered- almost too much. Very little diversity of opinion or cultures, has its own issues; but all small towns do. If you’re involved with your kids and your family you can easily work around this. "

    "bad area of the city, noisy at night, train going by three times during the midnight hour to six blasting, wrong way drivers taking the corners at 60 mph in the middle of the night, lots of shady looking characters in the vicinity, theres a reason the prices of the houses are so cheap"
