A colleague of mine sent out this website to me.
A nice and wonderful website for those that would like to pay a visit to penang.

http://tims-penang-traveltips.com

It is really a very complete site, covered till the extend of even providing the recently added public transport of Rapid Penang Bus Routes, together with the route details and Time Table.

A high recommended and must see site if you plan to come to Penang.
