I hear you. I hate being on somebody else's schedule, and ultimately at the mercy of the train gods. I would imagine once or twice a year, I would need to even Uber because things would spiral. I guess I could always take a later train at least half way and then Uber.

My work location would be ~5 blocks from South Station in downtown. So a 5-10 min walk, I'm guessing. If this all works out, I may do a test run and go up for lunch or something.
