Great pictures. So how long did it take you to get out there? I assume with the pup you had to make frequent stops (about the same as if you had a 1 y/o and a 3 y/o with you). How long did you visit each park? We would love to go west and I have these places on my bucket list (along with more) but just not sure how we could cram as much as I want to do in a 3 week trip.
actually the pup is three years old. hes full grown. he could sleep in the car for 8 hours at a time without wanting out.
but to answer the question, I kept it down to 450 to 500 miles a day, we took 5 days to get out, a bit more to get back because we also stopped at the black hills for a few days on the return.
from driveway to yellowstone campground was 2306 miles, coming back was a bit more because I took a different route.
