One of the things first time visitors to the NTTR (Nellis Test and Training Range) is drive the loop around the range. You head north on I-15, head up 93, get gas in Alamo, hang a left on 318, visit the ET highway sign, then head down 375. Pretty much you visit the front gate, see the LittleAleInn, then you are done. But to appreciate the size of the NTTR, most continue north on 375 to 6. Detour east on 6 to annoy Basecamp, then west on 6 to Tonopah. Get gas and finally head south on 95. The last stop is Creech AFB.
