Walking up a mountain to start then back down is 1/2 as hard as walking in to a valley and then climbing out even if total distance and elevation are the same. Relationships have been destroyed over such mistakes.
If you are going alone or small group. Tell people when/where you are going how long you expect to be gone what trails you expect to take and make sure you call them to report youre ok when done.
Please for the love of God, toast your tortillas in the pan before assembly. They are so much better. Other than that, this looks good.
