Whoops, just checked my post and found that the Tonopah link leads to Goldfield. Here's Tonopah: Tonopah
Also, if you're wanting to sightsee a bit, make a big loop from Vegas. Go up 15 to the Great Basin Highway, and to Tonopah via the Extraterrestial Highway.
I've never stopped in Alamo, but a person I know that was born and raised in Nevada absolutely loves the place. I need to stop in there this fall. You might want to check it out and see what they loved about it.
Stop in at Rachel for a burger (coupons at The Little A'Le'Inn website) before continuing to Tonopah (or stay there for a night). Then, when you head back to Vegas, head south on 95 to go through Goldfield, and later stopping (of course) at the Death Valley Nut & Candy Company.

Edited to add, just checked out the coupon for the burgers, and it's no longer 2/1, but instead buy 3, get the 4th free. Ah well, it's a vacation, right?
