There are loads of Hong Kong travel guides online, but they mainly touch just the mainstream destinations and strategies. So, I am surfing hardcore to find the instructive and unique websites to maximize our time while there. The following link barf is all the sites that I have gleaned at least one salient bit of info from. And most of the locations of the maps cite some info, to provide a reminder to myself as to why they were mapped in the first place.
