On my last trip I discovered that spiders (at least this particular spider) have reflective eyes! After loading everything on the bike and only having to break down and pack my tent, I scanned (it was still dark out) inside with my flashlight. I found something reflecting back at me in a far corner. I crawled back for a look and found a good sized spider staring back at me! That was a creepy discovery! I managed to scoot his butt (and eight legs) out of my home, thanking him for his company for the night.
I'm ultra careful about keeping my tent zipped up, but it was damned hot on this trip. I kept the door open about halfway to allow just that little bit more of a breeze in...I guess this critter saw the weakness in my armor and took advantage.
