Trying to get some things in order before we try to complete Puzzle No. 4.
Teams arrive in Huntsville in two groups, two hours apart. Looks like no great difference in the four teams completing the three tasks: Find the centrifuge; ride the centrifuge; fiind the computer; get thee to the pit stop. The difference between teams is the time spent on the centrifuge - the greatest bunch point of all bunch points. So the first group arriving at 12Midnight includes Bransen, Linz, Schroeder and Godlewski families. At the most give them 2 hours to do this so they arrive at the pit stop in that order by 2AM.
Second group, Weaver, Paolo, Gaghand and Aiello families arrive at 2:00AM and complete tasks by 4:00AM (Aiellos eliminated)
Therefore the first groups leave the pit stop starting at 2:00PM and drive to Anniston (1.5 to 2 hours) and then on to Talledega Museum and Speedway (.5 hour). So they should be completing their tasks there between 4:30 and 5:00PM
Second groups leave the pit stop ending at 4:00PM (times of departures between 2:00PM and 4:00PM given by spoiler from Huntsville). So following the same pattern as the first group they should be completing their tasks by 7:00PM.
Now do the shadows, rain, thunderstorm times fit the above scheme? Of course, we know that at least one team is going to get lost and be later than anticipated.
If all the teams get to the overnight campout, they would be leaving for Fairview Riverside Park between 5 and 7AM which would bring them there (again assuming that they can read maps correctly which may be too much to ask these blockheads) between 10 and 11AM.
Looking ahead to the afternoon of July 14 in New Orleans. Roadblock time? And time once again for the God-awful, terrible food challenge? TAR5 - Leg 4 St.Petersburg Caviar; TAR6 -Leg 6 Budapest Spicey Soup; TAR7 - Leg 3 Mendoza Charascariea Meat Challenge.
New Orleans is well known for its marvelous food: Jumbalia; Gumbo; Oysters Rockefeller; not to mention Bananas Foster!
