Oh, man, would that we could (btw, did I miss a call from you this Sunday? I have no messages, but it looks like a got a call from a London # while I was on the plane). Sadly, our layover is less than two hours, which between delays, the general layout of Heathrow, and the probability of long lines at security means we won't be able to count on getting out and in in a timely fashion. BAH.
