Having read slapshots inputs, I got quite a chuckle. But this person is right, if one is an "A" scaler, HKG is great. The $$$ do help ones acceptence levels. For someone to move to HKG now, on the B scale, with several kids, the first years will be very lean.
DB is a great place, but the if you have kids approaching 10 and up, you will quickly be aware that there is no where in DB for them to "hang out". If they try and kick a ball in the plaza, you will be told not to. If you try and skateboard, you will be told not too. I am sure they would be allowed to get pissed by the 7 eleven though...
We enjoyed living in DB, don't get me wrong, but the COS package I was on was starting to not cut it. As mentioned, the pollution levels are not changing. I do beleive HKG Govn't are doing their part, but most of it comes in from the north.
My advise for anyone who wants to make the move, ask as many friends as you can, but go visit yourself.
