I particularly like this moment because of the gradient of colors in the sky. The sun had previously set to the left, and the receding scattered blue was moving across the sky, mixing with the orange light from the sodium vapor street lamps that began to dominate the atmospheric glow.
Seconds later I had to abort because my light and pleasant drizzle had turned into a torrential downpour, the likes of which I'd never been caught out in before. My improvised oven-bag-and-tape rain gear would just not do, so I hurriedly packed it all in and made the long 1 mile walk back to where I parked. I definitely discovered the limits of my "water repellant" outer shell and wound up soaked to the bone. This was the first serious rain test of my rucksack, which I'm happy to report did quite well! Aside from the rain that got in during loading, everything inside was dry despite the outer shell being completely soaked.
Fun fact: I recently learned the technical difference between rain and drizzle -- take a look at a puddle; if the water droplets hit with enough energy to create a splash, it's rain. If it just creates a ripple and gets absorbed without ejecting any water, it's drizzle.
