Find an excuse to work in your front yard or garage. I’m always amazed at how the neighbors take that opportunity to talk. The fact that everyone there purposely bought behind a gate is one strike against you.
The individual makes a big difference. We have lived in 3 places here in SD over 15 years. In each place we found the neighbors to be very nice once the ice is broken. In the current, and hopefully last, location we know everyone on the street, always wave and talk.
