Are my posts rotting?

One of the first things Cassie and I did once we arrived in Bangkok was jump on a boat for a ride along the Chao Phraya River. The 1.5 hour ride took us down small throughways lined with houses precariously standing on rotting posts. We were greeted with many smiles and waves from the very sweet hearted families living along the rivers edge. It was also very cute watching all the old ladies busily washing dishes and laundry on their decks.
