Riding the Bus in Bangkok

Tomorrow Elizabeth and I are going to meet a local woman, Nuch, who will teach us how to cook some Thai food. She is married to a friend of Elizabeth's father who will also be joining us. To get to where we are meeting her we will be taking bus. I was just looking up how the bus works (routes, fares, etc.) and this is what I found about bus fares in Bangkok:

• Orange air-conditioned buses, 11-24 baht depending on distance
• New yellow air-conditioned buses, 10-12 flat fee
• Non-air conditioned buses, 8 baht
• Red buses (non-air conditioned), 7 baht
• After 10.00pm 1.5 Baht extra
• About half of the red buses are free
• Tickets bought on board, change is given
• All kinds of buses operate all routes

Literally copied and pasted from their website. What a set of fare rules! I guess we are going to hope for a red bus? That way we have a 50% chance of not having to pay? I guess? Confusing! We'll let you know tomorrow how it all turns out!
