Seeing this post about a guy trying to spend a week in the Mall of America reminded me of the time at Georgia Tech that a friend and I tried to ride MARTA, the Atlanta "subway", to every stop in the system. It didn't sound that crazy at the time. MARTA is basically two lines with (then) about 30 stops. We figured it would take us a couple hours.
By the time we got to the end of the east line we were bored to tears. We scrapped the idea. I'm trying to imagine a week in a mall.
