I would recommend searching existing photos and asking their owners, or private msg individuals who
may have the info. I would not recommend starting threads for an open discussion on locations which
may be deemed 'out-of-bounds' in Singapore.
Wouldn't want anyone to get into trouble because of a discussion here. Possibly lead to non-appreciative
attention as well (thrill seekers who look for such places to trash up or vandalize. Eg. Woodneuk).
