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. You can park on Ward St or at the parking lot of Cong. Beth EL Atereth Israel (the parking lot is across the synagogue). I asked a staff member and he told me it was OK.
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.
