Thanks Pasha who helps to post my response. I know this is an improper means and I won’t bother him anymore after this post.
We do make mistakes or wrong judgment and should confess and learn from our mistakes. Correct our behaviors and be honest. Forgive and give other chances to correct.
Yes, Interchange is a more accurate and appropriate description of the area which consists of round about and slip roads.
Hong Kong International Airport is very well managed in many aspects. Ground traffic control is one very good example thanks to the traffic control team setup. We rarely see traffic congestion or illegal parking on the airport island. Wilson Parking diversified and has gotton the contract to conduct ground traffic control, whether it itself is also a car park operator is irrelevant in exercising its duties in traffic control.
Absence of post signs is never accepted as an excise for unauthorized vehicular entrance, trespasser, or parking. No bank posts no robbery sign at its entrance for instance.
A response to S L Tai, we do have thinking power. Making good judgment needs evidences, not prejudices. I see people here keep attacking using bait and escalating that the improper feeding induces weakened body, and even reproduction etc. We simply cannot say eating rice induces cancer because people have cancer have eaten rice! If no one was seen using bait (far from using pin) and the bird was not seen taking bait, and with no dissection done, why do you suggest using bait cause its death?
