Yay for David Schwarz, as Mystery 10-4 shows West Sentinel as seen in August 1972. Attached is another mystery. This one, though is not numbered as it is a true mystery. I have it labeled as Dark Pool (River Group), but I don't think that's right. What do you think? Lastly here, thanks to several for reminding me of the informal name of "Nifty" -- I'd known it in the past but had forgotten. The term I used, UNNG-OTO (OTO = Old Tardy-Oval) originated, I believe, with Ann Deutch and/or Tom Hougham. Scott Bryan In a message dated 7/11/2010 5:32:19 P.M.
