evidence: Day 7 – Custer State Park, SD to Thermopolis, WY (Devil’s Tower) [...] The weather improved as we drove, and we were back in vast openness again for a while. We headed to Devil’s Tower, which really is always neat and beautiful to see in person, but also oddly frustrating as you can see it from like 20? 40? Miles away and you think "yay, we’re almost there" but you really aren’t and have another 30 minutes of twisting through the hills and countryside before you get there.
