I'm planning to get a 7 x 10 tarp, some poles, and some rope to make a simple shade for my one-person camp.
What, no one else noticed the size of his planned "shade"?
If all you are going to have is a 7 x 10, you would be better off just draping it over your tent or vehicle (whichever you are gonna sleep in) and hanging out in your neighbors shade during the day.
or just wrap it around you like a blanket
We have an obligation to make space for everyone, we have no obligation to make that space pleasant.
