Ashutosh goes to Puducherry in his Alto and brings back a complete package.. .. the route map, maximum speed he could touch at various stretches, difficulties faced, where he lost his way etc. And yes, the two posts guide is well supported with wonderful photographs, a treat to our eyes.

Driving to and fro was more fun than I had expected, even though I had to do it single-handedly the entire time.

At some stretches on NH66, you have patched roads, where you have to slow down a bit. Also, some farmers lay down haystack on the middle of the road to dry and crush by means of vehicles going over them. We also stopped at a very beautiful sunflower field by the side of NH66 near Chengam.
We lost tracks at both the places you are liable to. First, after the Krishnagiri toll plaza, where you need to take a left from under the flyover. We had instead gone up the flyover, and 15 kms towards Salem.

Hop over to his place, he is going to write some more on restaurants and the place itself.
