My choice would depend on the time of day I got dropped off. If it was towards the night, I'd work on a shelter. If it was earlier, I would get by some water.

I think a lot of wild plants taste really great! I eat a lot of them as regular food. Some do take more processing than others. I had some roasted wild roots just last night that were absolutely delicious! Wild carrots, Jerusalem artichokes, Elephant garlic. Wild carrots don't seem like they would be worth the effort, but it doesn't take long to get plenty of them.

Happy foraging!
