Stayed at the Colter campground of Grand Teton NP. This is a first-come, first served campground. The mountains seen from the Colter bay. So far, the BFG AT KO2 TIRES are very capable on an FW drive Sienna. They went through all national forest dirt road, unpaved roads without hesitation.
The feature in the Sienna Limited I appreciated most in this long road trip is the dynamic cruise control, it greatly reduced the stress put on the driver on a long, long road trip.
