Yes. The logistics of this are pretty significant. You can't just have a crowd of 7000 take a long walk together for hundreds of miles. They are not "living off the land". They are being supplied, transported and housed at tremendous expense.
One would have to assume they’re also being PAID.
You are correct.
That well fed clean non- disheveled “mob” if only 1000 miles from the border trotting at 4MPH for 24 hours/day would take 10.5 days to reach the US.
7000 people using 1 gallon of water / day would use 73,500 gallons of water while crossing either a desert or jungle while moving at a brisk 4 MPH for 24 hrs/ day for 10.5 days.
Moving at these speeds will burn approximately 100 calories/ hour. meaning they will need approximately 2800 calories/ day.
1 pound of corn has a little over 1500 calories.
1 gallon of water weighs 8.3 pounds.
At two pounds of dried corn, and 1 gallon of water/ day, each person must carry 100 pounds of rations with them (50# if on a starvation march) while trotting 4 MPH for 24 hours/day for 10.5 days.
Someone is assisting this”mob”. Someone is lying to us...
