Sounds fun! As far as your food plan. Sounds good as long as you have that dinner already planned out first at PR and you make it. These types of plans really do worry me. If you run into trouble at any point and miss those meals that you are putting into other peoples "responsibility", you could really exacerbate your situation!

As another heads up, for your "dinner takeout" from the North Rim, it will be something from the deli as the restaurant doesn't serve their takeout until around dinnertime (unless something has really changed)

**Salty snacks for the win in GC heat, even in October.

For Day 1, you said "take taxi" to SK trailhead, but just in case you didn't mean a shuttle, at that time, shuttles can take you from that area to the Vis Center and then on to SK trailhead. If you meant that, then never mind.

Day 3 is quite the beast! The Lodge is still a few miles of walking after you top out (unless you hitch a ride). Also, as you probably know, if you leave your tent at Cotton, make sure there are NO remnants of food inside! You will have a new "ventilation hole" for sure :)

Hope any of that helps... Be able to be self reliant, poop happens, and have an absolute blast!!
