A bit over a decade ago, I was motorcycle camping on a solo trip down the US West coast. Being a bit on the cheap side and preferring wilderness, I decided to make use of the Bureau of Land Management camp sites, where possible. They are free, somewhat remote and quiet (no hookups for RVs or any of that), which I really appreciate.
While heading South through Northern California, I stopped at the one near Ukiah, had a quick dinner, and went to sleep in my 2-person tent that I had been using for the trip. For some reason, I had my laptop out - maybe trying to look at some helmet cam footage. And, when I went to sleep, I was lazy and just suspended it, leaving its power LEDs slowly blinking.
I was awoken in the middle of the night by an animal rather forcefully trying to get through the side of my tent. I shouted and banged on the handle of my hatchet (hollow, glass-filled nylon, so it could be used to make rather significant noise). The animal took off, rather loudly through the brush near the camp site. My laptop, with blinking LEDs was right next to the wall of the tent where my "visitor" had been trying to gain entrance. So, I completely shutdown the laptop, ensuring that there was no blinking and failed to get any more meaningful sleep.
The next morning, once it was light out, I warily looked outside my tent to be sure that my "visitor" wasn't waiting for me. Then, surveyed the site with hatchet in hand and heavy sheath knife on my belt (Morakniv Companion - highly recommended in carbon steel as it's a great knife and still somehow cheap). All around the picnic table where I had cooked my curried lentil dinner were the large and unmistakable tracks of my large feline "visitor". Not wanting to stick around in case the mountain lion decided to come by to investigate some more, I quickly broke camp and made my way back to the road, skipping my planned breakfast for diner food.
As one can reasonably expect from this experience, I camped at the same campground on my way back North and return there to camp fairly regularly.
