I've lived in the DC area all my life..... DC is great, it holds our country's history and there is so much to do, be it visiting the government houses of one of the worlds super powers, or going to a sold out sports stadium, or the fabulous museums we have.
The last 3 days I have spent in Boston, enjoying the people, places, sounds and smells, and yes some of the traffic.
I spent several hours in Boston Common walking and sitting, thinking, taking it all in enjoying the clam of others and the reduction of the constant hustle bustle of city folks. I can't tell you the last time I sat in a park and did just that....sit! Its a sure bet if I am at a park I am either there for an event be it a race, a kids sporting event or some festival. I don't have the time to just go to go. But I also realize I don't want to when I am in DC.
I found myself walking to restaurants, to the Common, to Starbucks and to shopping. I wasn't scared or afraid I was simply blissful as though I had just been wrapped in a giant comfy blanket.
DC will always be home.... but if given a choice to have a new home city .. I would go with Boston hands down!
