And 39A, 32B, 36A...
If you want to ride NAC buses, you should go to kowloon. Most of
the NAC buses are in there.
Another route I recommend is 66 (Sham Shui Po Yen Chow Street
<-> Tuen Mun Tai Hing Estate). It goes thru Tuen Mun Highway,
a highway which is very long with lots of sea views.
Try 81M/86A/86B also! They all passes Lion Rock Tunnel (Not the
typhoon...)
And there are some new buses now, such as:
-Volvo B7RLE (w.h MCV Bodywork) (AVC)

-Volvo Wright (Euro 5) (AVBWU)
-Alx-Dennis E500 (Euro 5) (ATEU)
-Alx-Dennis E400 (Euro 5) (ATSE) (It was new... when in Feburary
this year...)

(Actually... They aren't really Euro 5... Just Euro 4 Engines
whit Filters... The only real Euro 5 bus in HK is PB6682)
