I had to be in Boston the last few days, and getting up this morning to drive home, I was like "huh, I wonder how much direct flights are from BOS today?"... and yes, I looked it up and there were flights I could make it to the event on time. It would have cost over $1000, but then I was like "eh, I'll skip it". I think I made the right call.
I feel terrible for the people who spent that kind of money just to get there. You made the right call.
