During prime rut? I think its half dozen, 6 the other situation....

being dropped off and picked up.....vs, driving to your stand parking walking in....I think helps, sounds like some benefits as opposed to those 2hrs midday....also hunting different spots etc....perhaps use walkie talkies and if the area is hot tell him you want to stay....otherwise follow his program....

This question makes me think back to my sport days, i recall my one coach and probably other coaches, saying, when at a camp etc....listen to that coach.....kinda makes me think, aside from some whacky idea....listen to his rules....he as you said is an accomplished hunter, has his own philosophies.....and has gotten the job done.

If anything you may want to get picked up, and speed the process along if possible, rather than 2hrs out of the field if you can do it in an hour....or rather than 3hrs...in 1.5.....either way talk to him, tell him your concerns and see what he suggests/says? Sounds like he'll tell you his reasoning, and maybe contradict your concerns/make you feel better, all I can say is I'd want to talk over every aspect I could prior to getting there.

Also maybe to shorten that lunch break, have a lunch packed....eat in the car....sure you can streamline it some ways, but I think he runs a solid ship, talk to references....see what they had though about taking 2hrs off during the rut to eat/shower? see if they liked it? if not what they would do differently.
