One observation from my travels:
Now that I'm old, a different type of creepy stranger hits on me! Whereas I was once pestered only by peers, recently I have had unwanted attention from a larger variety of socio-economic and age groups.
Though it is possible I was just too stupid to notice in youth.
Driving around in rural Texas I was amazed by many things, like abandoned houses, empty storefronts, and desolate car lots - all of which look as though they were thriving until recently. Like, say, weeks ago.
