ok in cambridge

London underground explosions today -- 6 underground stations and a double decker bus.
Mark goes to London at least 3 times a week for work. Thankfully, today Mark worked from his Cambridge 2 of the stations that were hit-- Kings Cross and Liverpool Street -- are where Cambridge trains arrive into London.

Whew.

It is all a bit familiar. And too close. Checking in with friends, alerting folks of being ok, nonstop TV coverage, questions, speculations, outrage.
