I used to live in the Boston area and I still have clients in Boston and need to go there periodically. I dont have any specific times I have to go, I just go when it is convenient or fits in with my schedule.
If someone needs to go to Boston, I can plan and trip and go there. So rather than me telling you when I am going to Boston, you tell me when you need to go to Boston. I am also in the towns of Brookline and Watertown and can drop you off at your destination depending on where in the Boston area. I am reasonable with the cost, asking $50 to help with gas and tolls. I am in the Easthampton area but can be flexible about picking up depending on where.
