Disclaimer: Most of the planning for this trip was done by my friends - Anagha, Vineeth and Sai. The entire drive was done by Vineeth, with the navigation support of Anagha. My contribution was limited to warming the back seat, cracking lame jokes and maintaining the Official Ledger. :P
Vital things you need: - Portable chargers for your cellphones (I am presuming you will use GPS), - basic tools for the car, - Copious amount of water, - Nuts, cookies and other quick-eats, - Handsanitizer, - Toilet paper (in case someone has a "breakdown" on the way :P) and music!
