From Reno:
Take Interstate 80 East from Reno, about 30 miles from Reno
take the Wadsworth/Pryamid Lake exit #43.
(The last cheap gas is available at the I80 truck stop at this exit.)
Take highway 447 north about 75 miles to Gerlach.
As you approach the town of Nixon don't take the Pyramid lake exit,
instead drive through Nixon and continue north to Gerlach.
About 5 miles before you get to Gerlach you will pass through the company town of Empire.
(The store by the road here is the only thing locally that can be considered a supermarket.
Stop on your way through to buy ice and anything else you forgot.)
when going through all these little towns - they are notorious speed traps. If in doubt of what the speed limit is, just slow down. If you can see homes and buildings near the road then you're most likely in a slower speed zone.
