Here's another one I wrote for January edition of the NPR Desert Companion magazine. A 1-2 tank trip starting and finishing in Las Vegas, NV.
(Cheat sheet: US-95 to Blythe, east along I-10 to Dome Rock Road to Quartzsite, north along Arizona Highway-95 to Parker Dam Road, north once more on AZ-95 through Lake Havasu, Mohave Valley, Bullhead City, crossing the river at Laughlin. West on Nevada Highway 163 to Christmas Tree Road and return to Las Vegas on US-Hwy 95).
