Anybody interested in getting together a day before Extro-4 or the following day (Monday?). I would love to spend more time with people...
Also, I got a couple of inexpensive hotel references:
Glenwood Hotel, 717 Sutter St (intersection of Sutter and Taylor) 415-673-0700, about $50/night
Grant Plaza, 465 Grant Ave (intersection of Grant and Pine) 415-434-3883, about $65/night
Will use on of them myself, unless there are still better options (like staying with a hospitable local person :-) )
