I just returned from Hong Kong and the city/state is replete with great photo ops.
As usual when I pack for a trip I forget one or two things. This trip I forgot to bring my tripod. One of the amateur photographers who works at the hotel where I stayed told me about a great camera store in Kowloon (a section of HK). The store is Sim City. The building is 6 stories high filled with camera equipment. The prices are lower than in the USA and very few items are gray market.
The stores appear to have every imaginable camera brands and accessories. They have loads of used lenses and gear.

One last note. My flight went thru Beijing and the Chinese version of TSA made me remove my camera from my backpack and they counted my camera batteries. I had five with me and the maximum they allow is two or three. I am pleased to say when I opened my camera bag only two were in sight.

In 1976 I was assigned to the Pentagon for what turned out to be an 8-year tour. A couple of years into that assignment- 1981, I was eating my sack lunch in the courtyard of the Pentagon. I noticed all the entry doors to the inner courtyard were blocked by armed military police. Very soon, President Reagan, the Secretary of Defense, Casper Weinberger, and Master Sergeant Roy Benavidez marched down to a podium. Within minutes MSgt Benavidez was presented with the Medal of Honor. I cried when his citation was read. I cannot believe any living person did so much to save his comrades. It was the most beautiful ceremony I have ever witnessed.
