honking your horn is just a way of alerting people you are there. Honking on the road is as common as chatter in a crowded room. Every road, except a few parts of mountain roads, has only white dotted lines separating lanes, and overtaking is expected. In fact, speed limits are hardly ever posted and highways have different speeds listed for different types of vehicles. Some horns are piercing and irritating, used by people who like to hold it down for a long time. Others are dull and softer, more comforting to listen to but probably in that condition from overuse. Then alot of the trucks not only had colorful painting, but had multi-tone horns. A lot of them sounded like a little kid playing with a trumpet.
I didn't take pictures of any of them, but most things like that can be seen in a Google image search for photos taken by actual photographers. I mostly took pictures of large-scale views that were impressive, or shots of the cities from our hotel roofs. The one above is in Dharamsala. One of the first things I realized was that no picture will do justice to the actual experience. At best, it gives you a tenth of the idea of what it was like to be there. A still picture can only say so much, especially a digital one. It may have been different if I had an expensive camera to make a film documentary of our experiences, but even that suffers from the lack of scale. Anyway, I look forward to exchanging pictures online and seeing the different perspectives of everyone else, also for things I didn't take pictures of because I saw someone else staking the same one I would have. A Facebook group or something may be in order.
