Borderland Biker: ... in memory of Indian Larry and Doo Wop music

Riding across Nevada on my Harley I’m passed by Elvis driving a ‘59 Cadillac convertible. Distracted enough to drift into the other lane, I’m nearly hit by an oncoming motorcycle. To avoid a head-on crash I ride off the road and down a steep embankment onto what I think is an old frontage road. I’m uninjured, but my bike is inoperable. Thinking the frontage road will join-up with the highway I was on I start walking, finally coming to an old abandoned diner called Styx Diner; parked outside is the motorcyclist I nearly crashed into. His name is Charon and he tells me I’m in the Borderlands, and the only way to return to my world is to cross through the old diner. But there’s a condition.
