Another interesting item in the "Etc." section of this week's "Pit Pass" is the anticipated return of Dave Mann (D.B. Mann Motorsports) as an owner in OW in the Indycar Series after a very long hiatus. In the late 1980s and early 1990s, he ran cars for Gary Bettenhausen and John Paul Jr.
IIRC, his only IRL forays were with Billy Roe and maybe Dave Drinan in the late 1990s, but I don't recall them being under the auspices of Mann Motorsports.
