Was stumbling Wikipedia when I came across the Pan-American Highway. It’s been officially recognized as the world’s longest motorable road, spanning an insane 25,000 kilometers!
I did the math, and in the end, if you use a car with a 15kmpl average mileage, you’ll require about 1666 litres of petrol, and around Rs. 83,000 for the cost of petrol (w/o taking wear and tear into consideration). Anyone up for a road trip?
Well, nothing still beats “Kayak across the Pacific” http://post.sathyabh.at/2075oidjpg-jpeg-image-800×595-pixels
