what about that old bus stop along old tampines road? what makes this one special is the fact that there's an old, big banyan tree right beside it!
IIRC, they filmed a scene of "the maid" there..... eerie stuff
This is the stone one I mentioned. I think it can also be found along the road outside new Home Team Academy, nearer to the Lim Chu Kang Cemetry (The Jewish and Japanese Cemetry).
Saw one of these while passing Upper Serangoon road today, as well as a few of the ones with the orange and white zinc roofs. Can't remember exactly where but I guess one could find it by driving or walking around the area.
