　　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. We visited

the famous market which was on water, and saw a lot of fruits and vegetables.

Everything is so colorful, and we have taken hundreds of photos already! Later

today we will leave for Chiang Mai. We will take the train north, stay in

Chiang Mai for two days, and then catch a bus to Chiang Rai.

　　Friday, March 30th

　　Our trip to Chiang Rai was long and boring. We visited a small village in

the mountains. The village people here love the quiet life-no computers or

phones. They are the kindest people I have ever met. They always smile and say

"hello". Kathy and I can only speak a few words of Thai, so smiling is the best

way to show our kindness. I feel good here and hope to be able to come back

next year.
