For a suggestion, we could meet in Parker Arizona, It is like 3.5 hours from Flagstaff to give you an idea of distance. There are several trails on both sides of the river, I am sure there is camping both dispersed and pay (I would check it out), the temps are 68 day and 40 night.....If we do a 2 day, 1 night, we can arrive, set up, trail ride, camp (or leave if not staying), wake and ride trails and head home (or stay if you desired more trails.....We can do moderate/easier trails...
Just an idea, LMK and I will put it together.
Main thing is being free the 19th (and 20th if camping).
