We don't have "communities" in our town. But we do have 55 and over apartments. My Mom lives in one that is very nice and secure. They have many activities, including music, dinners, movies, bingo, card games, and others. There is something to do all the time if you want to. It's like a little community in that everyone knows each other and they all look out for each other. They have underground parking for residents which is nice. On one floor they have a library and media room. On another floor they have a pool table, exercise machines, and a table for visiting or games. There is a huge community room on the main floor, a room for "free" items, a kitchen, and other rooms. I would retire there in a minute if my husband wanted to.
