From 128:
Take Middlesex Turnpike exit toward Arlington which is south ( This is Exit 32b going south on 128, I believe it is the same going North on 128 )

Go exactly 1 mile and take Right onto Hathaway.

From the East:
From Alewife, Rte 2 West to "Lexington St. Waltham/Waltham St. Lexington" exit (exit #54B). This exit is after the Arlington exits (Lake Street, Rte 60, Park Street) and just before the exits onto Route 128.
Take a right off the ramp (actually, your only choice). You are now on Waltham Street in Lexington.
At first light, approximately 1 mile, go straight. (If you played at Clarke, you'd be home now.)
Go through 2 more sets of lights to end of street (approximately a mile). At this (third) set of lights, take a left onto Massachusetts Avenue (you are now in Lexington Center).
At the fork bear to the right and take an immediate right onto Hancock Street.
At the fork, bear right onto Adams.
