Absolutely not trying to discourage you... just that I thought it was important to add the link. Alot of people have joined here since Joy's 'adventure' so there are many who might not have been aware of her story. Ultimately you are the best judge of what your family is capable of, and her plans were way more ambitious than yours... but the two things that raised flags for me were the time of year (which has been addressed pretty thoroughly) and elevation. I didn't have time to read through every post - have you given yourself a couple of days to acclimate to the elevation before dropping back into the canyon? Going down might not be so bad, but coming back out the other side might be more taxing than it needs to be.


P.S. Welcome to the board!
YMMV. Viewer discretion is advised.
