First, welcome back lady...good to have you around again!
It was much easier for me when I didn't live here, I would just post ahead of time when and where I was going to be. It seems it was easier to post ahead and pick an area, basically like throwing a dart and seeing where it lands.
Now, on any given day I get calls for virtually every area in and around Boston...not to mention NH, Hartford, Portland, etc. I've considered picking an area and just sticking to being there a couple times/week. Everytime I think it's a good idea, I change my mind. My best guess is Metro West...my idea of Metro West includes Newton, Waltham, Burlington, Lexington, and Framingham.
I have found in Boston there isn't a right or wrong place to be. If you're in Burlington, some guys in Newton/Waltham think you're too far away. Guys in the Tewskbury/Andover area won't drive to Burlington. Some refuse to drive into the city and others won't see you outside of the city. As I plan my trips outside of New England this summer I'm actually throwing ideas around about how/if to work Boston.
Again, welcome back...you have been missed.
