My armchair analysis for them-
I know they got one car and no bike.
Pocket of death glacier is pain in the neck, making for slow time, and maybe even the toe start.
Days are getting shorter.
Crossover still seems to require some downclimbing and possibly at night if they dont move quick.
Slesse Creek descent will require Drew and Ray to give ride since we be in the area (if they don't make a bivy) or walk\ride bike around.
My recommendation- bring your lightsabers guys
