Boston Marathon spectating

It is not difficult to find a spot to park your car and walk to the Boston Marathon route in a few minutes.

For example:

1. The parking lot of Cong. Beth EL Atereth Israel (the parking lot is across the synagogue) on Ward St used to be open to the public, but it is available to their members only now. However, you can drive  Cong. Beth EL Atereth Israel and turn right to Morseland Ave to find a parking spot there easily if Cong. Beth EL Atereth Israel's is not available. 
2. You can also park on Commonwealth Avenue near the Newton Fire Department. 

Military March starts at 6:00 and Men's Wheelchair starts at 9:02. They are the first participants one sees at the Heartbreak Hill, so should be at Heartbreak Hill before 10:00.
