Thanks Raj for your valuable inputs which quenched most of my queries. And Yes, This might be the longest reply I got for my posts too Hey Puntosat, that road is really a good one beacause of the beautiful scenery via Mudumalai sanc & Masinagudi. I would prefer that route if am with my friends or guys travelling. But its little dangerous to drive because you may encounter with wild life at any time. I have my relatives staying in Upper Masinagudi, which is just 15 kMS from Mudumalai Sanc. Whenever I go for a vacation to their place, we used to enjoy the wild life crossings across the road all time. WIld bison, Gazelle and even elephants which come down to quench their pant with the streams and lakes there post some threats. And also the road is not swift enough to reach you Coimbatore.I believe the Highways from Bangalore to Salem is kind of expressway which are broad and will take me home w/o having any stress while driving. I will consider your route suggestion next time if I plan a trip to Karnataka.
