In February we are in Chiang Mai 6 person. We rent already 6 motorbikes and get the permit from the owner to ride in Laos too. My friend contact a travel agency in Laos. They wrote a mail its not alowed tor ride with 6 bikes without a guide in Laos. They want a little bit more than 2000 US $ for a guide. We cant believe it. They say when the police catch us we become a lot of trouble. Who know is it right ? We want to go over the bridge in Chiangkong.
