We're heading to Yellowstone this June also to meet-up w/ Porsche friends who will already be there.
We're staying in Grants Village. We do not have a lot of time there but hope to see as much as we can. We also plan to drive down to the Tetons for a hike. Then roadtrip back to MN w/ our friends.
We can't wait. It will be an adventure!! Have a great time on your trip.
