I would make a couple of suggestion, encourage the occasional comunity night or afternoon, a barbeque or a block party, make it informal. Getting neighbors together in conversation can form good bonds. When people become an extended family they arte more willing to look out for and come to the aid of others in need.

Another idea, start a Tai Chi exercise group, meet at convient time, and work out together. Tai Chi promotes individual and group harmony.

I strongly encourage any woman on this forum to spend a little time and money and take self defense courses. It is a dangerous world out there and being knowledgeble of how to escape or stop and attacker, can be the difference between, life and death, living in fear or having good confidence.
