Don't know how much you know about Cambridge, but parking can be an absolute nightmare. Unless you have dedicated parking with your residence, you may want to get here then decide if you're better off without a car. Public transporttion is great and Uber is starting to pick up again now that 'surge pricing' (or whatever it's called) is being allowed. Send me a pm if/when you get here and I'll cook you a nice meal!
Wife and I are actually headed out to Santa Barbara tomorrow for vacation - that's where she's from.
