I'll never forget this magical scene I stumbled upon a few years ago.
(I'll attach a video in the comments—apparently I can't do both a photo and video in the same toot.)

@SJHoodlet Beautiful butterflies, but I'm still dissappointed the water isn't deep enough for swimming.
@kenjen The river widens in this spot, making the water shallower, especially along the banks. Farther up and down stream the river is narrower and much deeper, and swimmable (but exceptionally cold!).
