I've posted a couple of annual PSAs and swarm capture videos on Nextdoor.com, so I get a few dozen swarm calls every spring. But recently I realized I'd never seen a swarm until I started keeping bees 6 years ago. I now live very close to where I grew up (2.5 miles, as the bee flies) so it's not a change of location.
Given the general hysteria I observe when lay people see a swarm, I'm amazed that I never saw or even heard of a swarm when I was a kid.
When was the first time you ever saw a swarm? If it was before you knew about beekeeping, what was your reaction?
