LA to Yellowstone, + 10 more NPs in 20days

[CampnCat]

Hi,
Mom, Planning 3wk road trip/Camp'n adventure last week of Aug & into Sept, with 10yo kiddo, from LA to Yellowstone.
*We have an Access Pass, Incl free entry ALL Nat'l Parks & Monument (I think?) & 50% off CGs at NPs, BLM, NFs...+ More. Amazing savings!

((Edit: Had planned to pull TT, Now might possibly go with tent BC better CG Choices avail at this late date! Will also save $ on gas. My trip planning is stalled until I can commit to TT or tent... Pro/Con list not helping! ))

Anyhow, we Love beautiful scenic drives, love Nature & being outdoors- hiking, rock scrambling, plants& wildlife viewing etc. Can't wait to see YS!!
(Ideally wanted to be in YS midSept, but Ranger talks/hikes end 9/4/17 :/

Would love it if some of you experienced travelers, especially familiar with Nat'l Parks we've chosen, would comment :) Please pass on thoughts, ideas, opinions about itinerary?? Any feedback that might help make our trip go smoothly! & Safely!!
