Right back at you. I was also commenting on rate rather than saying that I saw one or 2 in the last 10-15 years.

Not all locations are the same though, so maybe there has been a noticeable decrease where you're at. Personally, I think I've felt an increase if anything.

These changes aren't always easy to spot. I live in a city that acquired a significant Ukrainian population over the last two years. Whenever I see a group of kids that biked to an arbitrary location and play, they turn out to be young Ukrainians. They do the exact thing local kids would do 20 years ago.
