Stop the presses—yesterday over lunch at the Grand Hyatt we snapped techie Steve Case…with a tie??? (David Rubenstein’s sartorial splendor, as a man of high finance, is to be expected.) Maybe that’s part of the Third Wave, Steve’s acclaimed new book arguing that we’re entering an era where entrepreneurs will use technology to revolutionize real-world sectors like healthcare, education, transportation, energy and food. Perhaps in said "real world," ties are back to the future. (P.S.: We see you eating in the background, GW president Steve Knapp and Rep. Barbara Comstock.)

Other stars on hand: Cassidy Pinkard founder (and now investor) Bob Pinkard, and Sigal Construction’s Gerry Sigal with son Michael…

…former Pepco CEO Dennis Wraase, HDR Architecture’s Steve Manlove, Avison Young’s Bruce McNair with son Bruce Jr., and Brown Advisory’s Meera Patel.

Meanwhile, Junior Achievement of Greater Washington CEO Ed Grenier, left, is celebrating his 20th year at the helm—remember to mark the occasion July 2. But Whiting-Turner regional chief Richard Vogel has that beat: he opened the construction giant’s DC office 31 years ago. Do you know it’s the second largest contractor in the US? Though in DC, its revenue is $1.2B to Clark’s $2B. But what’s a billion or two among friends?
