We've had some great final memory tasks in the history of the race, The amazing roadblock in Anchorage in Season 12, The flags roadblock in Season 9, Hello/Goodbye in Season 21, The greeters in Season 17 and the surfboards in Season 14. What would you like to see?
As a ultimate test of memory, I'd like to see a final roadblock where one team member had to remember the order of various clues throughout each leg of the race. You'd have a route info to start each leg and pitstop at the end but in between you would have to remember the various clues that were in the leg in order. I think that could be very cool to see.
