I just moved from California to Tennessee and only recently got to experience fireflies for the first time in my life. They're incredible :) I don't see them in the city, but that doesnt surprise me... there are tons once you leave downtown, though.
Intellectually, I knew they were ‘a real thing’, but that in no way prepared me for the reality.
Since then, it’s always been reassuring to look back and know that such wonder can still be felt by a grown adult.
Maybe it's a north/south thing, too.
I now live in NC where the bug is called a firefly and it has a single yellow glow near its tail and looks more like a fly.
