Why it ran this way

Down UT-9 out of the canyon in 90 F heat, battery up to 117 F, with a roadside pull-in at the Fort Zion ghost town in Virgin for a photo. 27.1 mi on 20 kWh, 1.36 mi/kWh towing downhill-warm, to the Zion-gateway Tesla stalls at Toquerville (where the first pedestal was slow, 4.35 kWh in 8 min, so we moved over for the real 51.78 kWh charge).
