If you really want to meet in Ely -
Then take Amtrak of Greyhound to Elko -
(No, not Amtrak - no baggage in Elko - only Greyhound, bleah)
Have your friend rent a car in Ely -
Then have him pick you up in Elko and drive back.
I really don't think there are any one-way rentals.
Your friend may be against getting in a car, though.
Then again - having you along for the last week and a half -
May be more important.
You do know that US 50 from Ely to Fallon is hot, dry, steep, and empty - eh?
Have fun - J
