Arizona → New Mexico · Interstate 10 / Interstate 19
Driving back into Albuquerque, New Mexico, after wrapping the agenda in Tucson, Arizona, tends to invite quiet reflection on operational efficiency: 603 km (375 miles) along Interstate 10 / Interstate 19 and another 5h 45m behind the wheel, not counting reception time, lobby waiting, and the actual meeting. Anyone returning from the place known as the second-largest city in Arizona and gateway to the Sonoran Desert reconnects with Albuquerque — the largest city in New Mexico and crossroads of the American Southwest — carrying the dual sensation of a job done and accumulated fatigue. To minimize tiredness, alternate music, a technical podcast and absolute silence each hour. Additional fuel spend on the return runs $50.42 (54.8 liters / 14.5 gallons). Equivalent reimbursement totals $259.29 at the $0.43/km tariff. On the Clara receipt, log notes about active road work seen along the way — the operations group uses that data to refresh the route's standard time each quarter.
