X rides are essentially an In State ride that has specific cities that must be documented and usually requires a start/finish at one of those cities. As I understand, it doesn't have to have a 36 hour Silver and 24 hour Gold component, but these could be done that way. Some states might only have SS1K potential, but NV has BB1500 and BBG potential.

Typical description is: To each of the 4 corners, through the center of the state each time.
From the link above:
The ride must be completed in the time specified for the traditional ride or as specified in the Ride List.
You may start at any location in the state. You may end at any location within the state.
You may not leave the state -- except for safety reasons, and if you leave you MUST re-enter at the same point you left it.
You must obtain a DBR every 350 miles or less.
Your official time is determined by the starting and ending receipts. PLEASE check these documents and make sure the clock and date are correct!
Spotwalla.com is required.
Remember it is YOUR responsibility to prove you stayed within the state. SpotWalla goes a long way towards this proof.
Since it appears no one has done a NV-X ride yet, it's up to you to plan your route and submit the ride as a new NC-X ride. You can ask
@Ira for his input on your route if you are not sure if it will be acceptable.
I would expect you to make your own choices on cities at the corners, but some examples would be:
Avi Smokeshop/gas station
10200 Aha Macav Pkwy, Laughlin, NV 89029
McDermitt Chevron
195 US-95, McDermitt, NV 89421
Jackpot Chevron
1104 US-93, Jackpot, NV 89825
Mesquite 76 Station
200 Mesa Blvd, Mesquite, NV 89027
And for the center perhaps:
Champs gas station
16 Main St, Austin, NV 89310
Alternately, you could choose to use the most SW point;
Harrah's in Stateline for a corner receipt
15 Hwy 50, Stateline, NV 89449
Gas at Chevron
217 Kingsbury Grade Rd, Stateline, NV 89449
Could look something like this:
Jackpot to Stateline to McDermitt to Laughlin
Or:
Jackpot to Stateline to Mesquite to McDermitt
You could choose hwy 306 instead of hwy 305 for one or both runs as well, as long as you crossed your chosen center point.
