I haven't been in Hong Kong for around a year. Coming from a small town like Alamogordo, New Mexico back to a big cosmopolitan city is overwhelming. It's nice to have all the convenience of a modern place, but seeing thousands of people just at one zebra crossing (crosswalk) is disturbing.
If you happen to travel to Hong Kong, try to avoid the rush hours at Causeway Bay. That will save you a lot of headaches, and possibly money too. The zebra crossing right outside Sogo Department store is one of the busiest in Hong Kong and many pickpockets are at work there. Keep your handbags and wallets close to you. Do not swing your bags at the back. Your wallet or cell phone will be gone after you cross the road if you do so.
Don't leave your belongings hanging on the chair in a restaurant or on the floor either. Pickpockets are faster and smarter than you think.
