Yellow

The "yellow-brick road" is a long, twisty corridor that runs through most of the buildings on the NUS campus. Because the campus is build on a ridge, the corridor is usually high above the ground; in my building, it runs through the fourth floor.

The corridor is important because, when it's hot in Singapore, it's very very hot, and walking to class in the shade is a good thing. When it rains here, the rain means business, so walking to class undercover is important even when it's not hot.

Much of the corridor is lined with picnic tables, power sockets, and internet connections, so you can take notes or do Web research anytime you like. The internet sockets (there are thousands and thousands) may soon be replaced with WiFi (802.11b) connectivity.
