Edisonic--don't know what age group your friends are in, but, what they saw that night was what I saw many years ago when I first saw Brooklyn.
Deserted, grey, dirty, ramshackle, covered with graffiti broken windows and mean looking people. This was Flatbush Ave, and I had missed Brooklyn's heydey, the beloved city of gardens, neighborhoods and safe traveling. Great people came out of there.
But I stayed there for a few years and I knew I had lucked out. All of the city's beauty was being rediscovered and there were people willing to take a chance on it. Today it's one of the greatest urban areas to live in, if you like cities.
Buffalo can do the same, but it takes work, faith and lots of money and endurance. Don't worry about your friends. They've seen it all.
