The season the show tried something different and pulled back from. Ten teams of four — parents with their kids — ran an eleven-leg route that stayed almost entirely within the continental US, with short detours into Mexico, Costa Rica, and Canada. The four-person format crowded the vans and slowed the airport-to-airport rhythm the audience had come to expect. Phil Keoghan hosts with care. The experiment never returned.
Slot #13 of 38 in the The Amazing Race Editor's Canon. The seasons on either side show what I ranked it against.
