Yes, Congrats to your wife, for Qualifying. I have run Boston 3 times, My wife Carol, after many tries, tears, and years of hard work finally qualified and we got to run it together last year. (we took Alaska air) As you probably know, It is quite the accomplishment, even Just to get accepted, and the celebration there is way more than just the race event, So be sure to partake in many of the Pre and Post race activities as possible. I found that the T (subway) works really good for getting around, to and from your motel etc. Buy the one week unlimited (think that what it was) option, as someone else, said watch it on race day as some of the stations are closed. Have fun, and if this is her first Boston, I'm sure, it will be the most memorable run of her life.
