It's been a few weeks back since the last post on this.
Driving all the way from Miri, Sarawak to Kota Kinabalu, Sabah (about 447 km) via Brunei was quite tiring, and that's the longest trip I have driven in my life. That was a really good experience....
Travelling through a lot of checkpoints (about 4 checkpoints), passing thru different country (Brunei), different cultures, and the most important.... strictly no more than B$10 petrol to be filled up for Malaysian cars (started from 1st October 2007).
Anyway, we might be going for another trip from Miri to KK again soon...
