In most returning racer seasons, there apparently haven’t been a final memory task. TAR 30, with no returning racers, had such a task, TAR 31 with returning racers did not.
Colin and Christie are born, raised and live in Texas. Christie has said she grew up in east Texas. As Colin mentioned during the Netherlands lag, he grew up on Padre Island across from Corpus Christi. Both attended the University of Texas in Austin and met there, a year before TAR 5. Both moved around a bit but settled in Austin before either of their boys were born. That should fill in what is available on social media.
