Pi Year-ROUND
Kudos to all our well-rounded friends who sent accounts, including photos, of their March '09 "pi day" celebrations from CA to NY to GA to IA to MO and beyond.  Note that summer schools sometimes celebrate pi July 22 (22 divided by 7 approximates pi). November 9 -- the 314th day of 2009 -- is a great date for Fall Semester celebration of pi.  Meanwhile, we'll be waiting around to hear from more of you!
