Some of these 'singalong' parlors still exist, faded and tired but otherwise unchanged, offering a taste of popular and cheap entertainment from a past era. How these survive in anyone's guess.

If the instability of the freelance photographer’s way of life isn’t for you, you can always find a day job that involves traveling. Then you can go to lots of places, be paid for it through your job, and do travel photography in your spare time. Jobs like flight attendant, global salesperson, English teacher (or a spy!) are just several of many professions that let you visit your dream locations, without being too risky on the financial side.

Make use of people to give your images life and scale. If the facade of a particular building appeals to you, the picture may be that much better if you show people walking in front of it.
