Boat trip somewhere off Phuket

I like it. You should come up to CM if you like to shoot caves. There are several caves within easy driving distance of the center of the city. The whole area is limestone karsk. I suspect there are a lot of as yet undiscovered large caves still hiding in the mountains. There is a cave in Mae On is about 30 mintutes from town but I have never seen another foreigner there even though it is only a couple of minutes from the San Kamphaeng Hot Spring. Unfortunately the lighting is such in the deeper parts that it is impossible to get good shot without a lot of additional light.I have a trunk full of old Strobonars I plan to have shipped. They trigger circuit uses a household plug so creating a large slave system can be done with parts acquired from an electric shop rather than expensive PC cords.

Thanks for the tip.

I'll be in that area soon as it is, so I'll seek out the sites you refer to.
