Went to the Colonial Inn! We had a "Linner", Lunch/Dinner at around 2:30pm so no problem getting a table. Actually it was a beautiful day, so we got a table out on the porch. Very good food, good service, great atmosphere. I can certainly recommend it. A little expensive, but what I expected for that type of a good restaurant in an area like that. This was on a Sunday, so we found a great place to park - right down the street behind the Colonial Inn is a drug store and bank parking lot. We didn't get to the Concord Museum in time - we heard that it is worth visiting. Next time!
We went to the Minuteman National Park visitor's center and saw the 20 minute presentation - really cool. Done very differently. Looks like you are going to see a stage show with props and all. But they use video, lighting, and LED maps to explain about the very beginning of the Revolutionary War. Very good.
Also went to the North Bridge. Beautiful "visitor's center", which is a gorgeous brick colonial house overlooking the bridge (it is actually the 3rd bridge since the original). Quick 8 minute video talking about the bridge, and that it is the location of "The shot heard 'round the world". The shot heard round the world was actually not the first shot in this battle, but it was where the first shot was fired by militia who received a direct order to fire on the King's troops. Also saw the Minuteman statue - Farmer holding a gun in one hand and a farm plow in the other.
I was a little surprised at how, well, "small" the visitor centers and locations are. Considering that the events that happened were world changing. But as my wife pointed out, it was really a small skirmish - that started the Revolutionary War.
We did not get to Walden Pond.
We had a great weekend, and thanks for the tips and ideas!
