We have a driver, no rental car. There is absolutely no chance we would have made it here if we had to drive ourselves. There is absolutely no signage, and so much road construction/closures with no marked detours that our driver got lost and had to ask for directions. Google said it would take 3 hours to drive from Mumbai to Pune, 3 hours after getting in the car we were still in Mumbai.
For touristy stuff, we went to see the Gate of India, the Taj Mahal Palace Hotel (where the 2008 Mumbai terrorist attacks took place), Marine Drive and the Old Bombay train station. Stopped at some shops and bought some souvenirs and gifts for my girlfriend and my mom.
I didn't bring my hat, mookie. I wasn't going to deal with that thing for 20 hours of flights. I do have my boots, though. I didn't wear them today, I wore shorts and athletic shoes, since it was 95 degrees out. On our way to Pune we drove past a place called Monty's Country Bar, I should have had the driver stop.
