current 3L here - I was watching Barbri videos on 1.75x speed which reminds of the time I was watching all JY vidoes on 1.5x speed. Contrary to my user name, I actually never got that 173 on LSAT, but did get into a T20 and will start in biglaw starting next summer.
Looking back it's amazing how much I've changed over the last 2.5 years of law school. I'm turning this into an AMA, so if you have questions or need encouragement ask away.
I chose D as well! I remembered recognizing that a stadium enables athletes to compete, but I guess irrigation and farming is more direct? I don't think D is wrong but just B is better. The "in the desert" part definitely throws me off a bit.
