I'm glad it's on the way home and not on the way in to the office; ya gotta get home...
I actually prefer to ride against the wind in the morning because I leave pretty early and get in extra miles most days anyway. On the commute home it's usually been a long day at work; I'm tired; it'd be nice to have a little bit of help. Alas it never works out that way.
