Taking in Ko Samui was much easier and scarier using motorbikes. For $6.50AU we had them for the day. In Thailand, there are road rules, but they are ignored. We were the only people wearing helmets. You give way to whoever has the most momentum and blast your horn at every oppurtunity to remind people that you are there. We saw GrandMother and GrandFather rock - the most photographed location on the island for their uncanny likeness to the relevant genitalia... Then we were off the bikes and heading up in to the rainforest.
