Just like there are interesting phenomena and interesting people all around anywhere and any time, there are interesting memories. They may pop up just from thinking about someone I knew or some place I lived or visited. My wife and I have lived in Maryland and Wisconsin. In addition, we lived in London for 2 months twice while leading groups of college students on semesters abroad.
I am focusing on places we stayed for a while, not trips and tours, but we have had quite a few of those, too.
I don't feel I have been any place that calls to me to be a resident there to a special extent. I am confident that if I pay attention to what's going on, including what fascinates me and interesting things I have read or heard about, all locations can be interesting or boring, depending mostly on me.
