I thought I was going crazy. When I broke down my TT Rainbow, my new GG polycryo groundsheet was nowhere to be seen. It's really light and thin, so I checked the bottom of the tent to see if it was stuck to it, and it wasn't. I kicked around in the dirt to see if it was there. It wasn't. I walked around to see if it had somehow blown out from under the tent (even though I weighed it down with rocks). Did see it anywhere.
I thought maybe somebody stole it? But that didn't make sense, because there was a WM Summerlite and NeoAir inside the tent, and surely they would have stolen those too?
So was I crazy? Had I not put the sheet down but thought I had? I had no explanation.
Until just now I looked at the pictures from my trip, and I have definitive proof something ate/stole it.
See this picture, where you can see the sheet sticking out from underneath the right side of the tent:
Now see this picture, from the next day, before I realized the sheet was missing:
Notice all the little silver spots? That's duct tape, patching holes in the netting 10-11, if I remember correctly. I noticed the holes when I laid down for a rest, after my day hike. I had no idea how they got there. I blamed my cat, who likes to attack things. I'd had the tent set-up for seam sealing the week before, and she'd gone at it, but I'd shoo'd her away. I assumed she came back, even though that was a lot of damage for her to do.
Now I had my answer. Some animal made the holes as it was pulling/nibbling the sheet out from under my tent.
There were ALOT of deer wandering throught the camp (Little Yosemite Valley). Do deer eat plastic? Also, I saw some crows, and I know some birds like shiny things. But this is a 46"x96" ground sheet. That's a big piece of plastic.
Has anyone ever had this happen to before?
