Becareful of your hands
While you are on the boat trip, remember do NOT hold on to the edge of your boat. If you can see from this picture, sometimes boats glide by each other with no space in between them. It is wise not to grab the edge of the boat especially during 'traffic jam' on the main canal.
Watch your step when walking to the market!
We walked along the canal to get to the floating market one morning and ran into a very large lizard roaming around a local farm. No idea what it was but, it could probably do some damage.
