Ahhh, the jungle calls, so Oak answers. Took 6 hours from Katie to get to Sen Monorom, on top of a pickup truck loaded with fruit, things, chickens etc. and getting stuck twice
Took 10 hours to get out of there while riding on top of a bunch of finished wood products, getting stuck 3 times and having to hold on for dear life the WHOLE time as the perch was so precarious that letting go while the truck was stopped I'd slowly slide off. OH, did I mention it rained most of the way?
BUT the place was beautiful and I would go back in the dry season in a cambodian minute.
