So true. It took DH and me to do it.Welded wire fencing rolls have an excellent memory, and it would've been nearly impossible for me to try and unroll it from post to post, then attach it, by myself.
If they sold carrots with the tops, somebody trying to follow a recipe calling for
"2 cups of grated carrots" might include the tops in those two cups and end up with not such a good carrot cake. Which reinforces your premise that the USA is severely lacking in food and nutrition education!

We had the same thing in my school. All the kids took 12 weeks of Home Ec (cooking and sewing), 12 weeks of wood shop, and 12 weeks of art. I think it was a good idea for everyone to take all three classes. I learned respect for tools, made a couple of projects.I'm 62, and I was forced to take "home economics" in middle school along with all the girls, and all the boys had to take woodworking. The class was pretty basic, I think the most complicated thing we cooked was grilled cheese-and-tomato sandwiches, and there were no "economics" involved, which might have been useful if they'd taught us "you can save money on greens if you cut off the carrot tops, cook them separately and serve them as a green vegetable."
