Dude, you gotta get out of Mayberrry a little more often(Woosy boy told me to say that
)
Take Mass Pike East to Interstate 93N to Boston. Enter 93 N Tunnel. Take Exit 26/Storrow Drive. After exiting, stay in the left lane and follow signs for North Station. Make a right at the next set of lights onto Nashua Street. Follow Nashua Street until the end and make a left at the lights. The FleetCenter will be on your left.
There's parking almost everywhere. Basically the closer you get the more $$
