Realization of the day:

I have not slept in the same city for four consecutive weeks since February.

Presume the unscheduled time to be Philadelphia, and be astonished:
Early March: Ithaca, three nights.
Mid-March: NYC, one night.
Early April: Long Island, one night.
Late April: L.A., fiveish nights.
Early May: San Francisco Bay Area, twoish weeks.
Mid-May: Washington, D.C., four nights.
Mid-June: San Francisco Bay Area, one week.
Late June: Santa Cruz, CA, two nights.
Late June/Early July: San Francisco Bay Area, one week.

I go back to Philadelphia on Tuesday and, presuming that I don't need to go up to Ithaca to look at apartments, I'll actually be there four weeks.
