Rob--
        I saw 27 over the narrow compass of my back yard on the 28th; surely
there were more, but I didn't take a walk. Why the twin peaks, do you
think?  Minnesota had a one-day count of over 30,000 on 21 Aug this
year. Some maxima from Columbus: the highest twilight counts of fall
movements usually come from late August-early September, and include
3000+ on 9/3/1976 (Thomson 1983:206), 2500 on 9/3/1992 (OC 16(1):21),
and a description of circle-soaring by “at least several thousand” over
the OSU campus 9/3/1968 (Mueller 1970).  Later in fall, 224 were
observed 10/3/2006 (OC 30(1):20).  One entered the OSU campus’s main
library on 10/22/1965 (WCB 11:46).  Record late was one lingering
11/20/1975 at High St. and Morse Rd. (J. Stahl, WCB 1(20-21):42).
Something magic about 3 Sept maybe.
