I wasn't feeling keen beforehand, I find travel extremely tiring and the drive to Baltimore to where we're staying and then out to our friend's house seemed like kind of enough activity for the day. But it was actually incredibly nice to get in the pool, and reinforced my desire/commitment to swim a lot in December - I've really been missing it.
Can't remember now exactly what I did, but c. 1000 yards along these lines:
3 x 100 drill (RaLaCuBa, front scull, fists)
4 x 50 drill-swim in IM order
100 free easy
