Prevented from going north to Phonsavan at Vieng Thong. My plan was to ride from Lak Xao to Phonsavan, so after a night in Las Lak Xao, I rode hwy 8 to the turn off, and started ending north. When I got to Vieng Thong the police/army? told me I couldn't go any further, indicating with hand signs that there was shooting further north. One guy I meet in Thakhek said the vietnamese are logging in that area, and sending the timber to canada and they don't want people with motorbikes and cameras poking around. Another in Savannakhet said there has been fighting in there with some unhappy Hmong people who had been sent back from Thailand. What ever the reason, I had to back. The turn off on hwy 8.
