No idea why this popped into my mind just now, but I feel like sharing: A few years ago, I had ridden my bike about 5 miles to a store in the mid afternoon. By the time I was heading back, it was already late sunset. So I decided to take a shortcut down a nature trail to get home faster.
As you can imagine, the sun went down almost completely before I made it half a mile down the three mile trail... Through the woods... With no streetlights whatsoever... And with lots of wildlife activity, ranging from deer to alligators. Occasionally I would see two glowing eyes reflecting my inadequate, dim headlight. I had my bike in high gear the whole time and pushed my legs so hard it felt like the veins were going to pop. Never again.
