Scottsdale and Retromobile. Catch a flight to both

When Phil Collins decided to play at both Live Aid concerts on the same day in 1985, first in London and then in Philadelphia, he used a combination of Concorde and time zones to pull it off. Some collectors may well be tempted to try the same tactic to put together the three auctions of Scottsdale, Arizona, and Paris, at Retromobile. Concorde may no longer be with us but the journey only takes a day, so it is possible.
