We took the time today to go out to Concord and Lexington (mainly because of the trip advisor reviews on the Liberty Ride. While doing the Freedom Trail in Boston is an amazing experience, the Liberty Ride was better. We took the red line out to Alewife (end of the line) then you catch the 62 or 76 bus out to the history museum at Massachusetts road and marette road. The buses automatically announce off the streets as you approach each stop and as soon as you hear Marette road, hit the "stop requested button" it is about 20 minutes from the time you leave the bus terminal at Alewife. You can see the history museum (where the Liberty Ride trolley leaves from) from the bus stop, about 100 yards. Get there by 9:45am as the trolley leaves promptly at10am and there is only one trolley that does the hour and a half loop. I highly recommend this outing. Most of the museums and places to see along the route close at 4 pm. That is why it takes more than one day to see it all, however if you stayed on the trolley from 10am till 11:30 am then raced around from site to sight in your own car with a short lunch, it could be done in one day.
