US election series: 48 hours to go

Then: Monocle’s Chris Cermak reports from Donald Trump’s rally in Pennsylvania and we hear from Georgina Godwin down in South Carolina. Plus: we meet the team at WSP working to revamp the Hartsfield-Jackson Atlanta International Airport and meet the architecture duo at G+G working hard to preserve Atlanta’s historic landmarks.
