in 1968, when things were a bit crazy, two A 26s were at the Reno Air races

Dwight Reimer's Douglas A-26 "Cotton Jenny;"  and  Wally McDonnell's Douglas A-26, "The Mojave Kid,"

Wally must have been a hell of a character, as he owned a total of  54 aircraft, and included DC-6's and -7's, a B-17, countless WWII fighters, helicopters and seaplanes.
