Follow this link and enter Lake Titicaca, Puno, Peru for this week's answer, and you should earn 2,000 Priority Club Points. You must enter the answer today for 2,000 points. If you wait until tomorrow, you'll only earn 1,000 points, and if you wait until Thursday, you'll only earn 500 points. After that, you'll get nada.
Tip of the hat to Gary.
