most people will not move to the city early (usually they get to the city a week before classes start). i go to a med school on the east coast, and everyone that i've met that come from california searched for apartments online, signed a contract, took the flight to here, and bought a car, all in that one week period. i don't really see the point of moving to a new place in may or june... you might as well just enjoy life during the summer, do everything that you wanted to do, and spend that time with family and friends, because once classes start, you will be practically isolated from all of that. as for trying to get to know a new city, there's no harm in that. but be aware that with all the studying you will be doing, it won't make much difference to know where all the hot restaurants or clubs are since you won't have time to go anyway.
