Buses load up the "caravan" walkers...
Care to revise your estimate?
No, we have been shown trucks with jerks hanging all over them for almost a week so that has not made a lot of difference. For the first 3 days the Mob was averaging 17 miles per day the last 9 it has been moving at 22 presumably after transportation has started.
It is not easy to organize a Mob of 3-7,000 people. For example, the trucks/buses can make a delivery then it has to dead head back down a highway which is not clear. It is unlikely that the down trip could average much over 50 mpd given the look of that highway. Thus, the actual speed would be about 25 mpd.
There is also still a problem with supplies.
But the information about this is very sketchy and it isn’t even clear how far they have to go.
