On the trip to Ogden for the golf tournament this past week I did the big circle counterclockwise around the Great Salt Lake.  Nevada to Utah on I-80, and Utah to Nevada on UT 30 and NV 233.

I've crossed Nevada's borders at most of the places where state highways cross, and also at a good number of places where neither state's road is a state highway.  In the latter category, there are a couple of local streets on either side of US 50 near the Stateline casinos, and others would include the Aztec Road and the new Bullhead Parkway bridges near Laughlin.  One crossing I can't remember making is on the Winnemucca to the Sea Highway, NV 140 and OR 140.  There's no destination from Tahoe where it would make any sense to use that highway between US 395 and Denio Junction (NV 292), so it would require making a specific point of driving that rather lengthy road.

Coincidentally, and on the same day as Rothman (and attending the same lunch), I invariably used Routes 4, 9, 119, and 123.  And also I-89 three times.
