Dear Sir, Mr. Sanj
Yes, I am Native in Bangkok and live in Bangkok for 25 years, Before Move to Study and work in North Carolina since 1974 = that another 39 years.---And I go back home every 2 years, Yes, My Home in suburb of Bangkok too. Yes, Bangkok is one of the most beautiful city/ country in this world, But Past 5 Years, The Economic in Thailand/ Bangkok are so bad----Be careful about to go any where, special in the Night time with your Camera equipment---You might lost your equipment to 2-3 bad guys in the night of Bangkok--If you Lucky, In the Worst case you might lose your Life too----Yes, My Suggestion, When you stay in the Hotel in Bangkok, Try to be friend with the Hotel manager, and ask where to go in the night time in Bangkok, But ask the manager to hire the out of duty/ the Security staffs in that hotel and pay him as your body guard and the tour-guide too. Yes, Although I am Native in Thailand and in Bangkok--I must go with my friend 2-3 of my friends, when I go to shoot the Night time or early morning Photos.
I am sorry, but this is quite shocking. I have been in this part of the world for around 20 years, have spent a lot of that time in Thailand, and what you are saying is very over the top. I doubt Sanj is going to start taking pictures in the slums of Klongtoey, or any other iffy area - he is more likely to be in well populated places like the Grand Palace which is beautiful at night.
Thailand is one of the safest countries in the world, but of course you must be careful, and of course even more at night, and even more if you are a single female. But it is much safer than many western countries.
Common sense is important, because at night a lot of funny business goes on and you do not want to be taking pictures of that, or even to be thought to be taking pictures of that.
But asking the hotel manager to organise for body guards?!! 555 that is so funny, it makes me cry. What makes you think you can trust the "body guards" of a hotel, when you have basically told them that the stuff you are carrying is so valuable that you and it needs guarding?!! They also earn a lot less than the stuff you are holding.
Anyway, I am not having a go at you Surapon, but you do paint a very dismal picture of a very colourful place - which quite frankly is very un-Thai.
