Sometimes purposefully I will drive up to the gate smile and leave. Screw them.
Let me add a sad story. A beautiful place up past Doi Suthep was full of the most beautiful ancient hardwoods. Until last week when the staff cut down 15 of the most beautiful spiritually life giving trees. I thought jeez, were they dangerous? Then I drove up a bit further and saw all the cut trees stacked up for export to China or maybe Bankgok, who knows. I was blown away, what person can do this? OK, ya starving but they are not. Doesn't take Government employees any where to start to think they own the park and the last thing they want is anyone visiting their private space.
