Boating in Halong Bay

We went on an awesome tour of Halong bay (I am still on the tour actually) Halong Bay is a maze of jutting mountains in the calm China Sea. There are 16 of us on this tour: an older German couple (both chemistry professors), a young Spanish couple(scuba instructors and internet cafe owners),and Isreali couple (undergrads), two Brits on holiday, an Aussie, a Canuk (both on a year adventure), and us. We first went on a cave tour which opened up to a huge cavern. Last night watching the sunset on the top of this boat and then talking with these people under the stars was definitely a high light of the trip.Today we went on a trek in the blazing heat and 100% humidity which is always fun. We got to a look out. Then we went kyaking to a beach and went swimming. I was with the guide. I really enjoying talking to the people here in Vietnam. I think meeting people from different walks of life is the best part of traveling. He was 25 and from a small farm. He learned English and became a tour guide. He was shocked when I told him there were 8 kids in our family because the law in Vietnam is one or two ( more than that you have to pay) We then kyaked to a fish farm and I had to balance across 2x4" passing over the fish and shark cages in order to get back to the boat (it was pretty intense.)We go back to Hanoi tomorrow. I hope everybody is doing alright. We have about a week left (2 days in Hanoi and the rest in Lao.)So i will see you soon
