Signs

1.  With graduation ceremonies canceled last year, families of seniors graduating from high school put out yard signs with the schools' names, colors, and emblems. This year, there is a yard with two signs, one for middle school just left, one for high school to be started. The signs are a novelty, and informative: I'm not surprised that so-and-so graduated from X, but who's the kid that went to Y?--I never saw a teenager at that house. I know three students in the neighborhood due to graduate from the same high school next year. I trust they'll get an in-person ceremony, with or without a yard sign.
2. About every two hundred yards along a stretch of Rock Creek, one sees two signs close together: "Stay Safe/Stay Dry" and "Mantente Seco/Mantente Seguro", each with a statement in smaller type stating why one should stay out of Rock Creek. At greater or lesser intervals, there are people in Rock Creek. Some are small children, some teenagers, some adults. This happens even where one often catches the whiff of sewage. My wife has spoken to some of the people in the creek, with no greater effect on them than the signs had.
