Saturday, March 24th We have arrived in the hot, wet city of Bangkok. This is our first trip to Thailand(泰国). All the different smells make us want to try the food. We are going to eat something special for dinner tonight. The hotel we are staying in is cheap, and very clean. We plan to stay here for a few days, visit some places in the city, and then travel to Chiang Mai in the North.  Tuesday, March 27th  Bangkok is wonderful and surprising! The places are interesting.
