This is what i found on the ma.gov site (Massachusettes), in the FAQ section:
"Q#4. Is a foreign licensed driver required to carry an International Driving Permit (IDP) when driving in Massachusetts?
A. No. Although some countries require a foreign motorist to possess an IDP, the United States has not done so. It is suggested, however, that he/she carry an IDP if the foreign license is not printed in the English language."

The answer above mentions "United States" and not just Massachusettes.
They have listed the countries in an appendix whose licenses are accepted in US. India is there in the list.
I asked a couple of people here in office also and they also said that if visiting for a month or two, you can use ur indian license to rent and drive a car.
Anyways, it seems its much easier to get an IDL from Patiala, so i am gonna do that now. Better safe than sorry!!
Thanks for all your replies. Once again TBHP comes to my rescue!
