I had another good flight yesterday, although it started interestingly.
After the run-up, I got cleared into position and hold on the numbers while traffic ahead departed. While I was sitting there waiting for permission to take-off, my instructor handed me the hood and said, “Here, put this on.” I think I said something like, “You want me to do what? On take-off?” He then explained the dynamics of it all and said that I might have to demonstrate this during a checkride. It was really strange rolling down the runway at full power and not being able to see a darn thing, and according to my instructor I did a good job of holding centerline, but maybe he was just blowing sunshine up my skirt. 
We had a brief discussion about this during our climb, and while I understand the purpose and need to demonstrate this, I explained that if I couldn’t see the runway from the cockpit, I probably would just choose to stay on the ground. My instructor agreed with my statement saying that it if visibility were really that bad, it would probably be a wise choice.
