Nearing the end of the book, on my edition pg. 282 Roland surveys a crowd of miners.

"He went back and I surveyed them. Luka was the oldest by far."

But a few pages later (286), during the same scene, after Roland has the men line up by age, the man AFTER Luka is described:

"After him came a man nearly as old, with a mangy white mustache, dirty gray hair falling to his shoulders, and a sinister, squinted look in his eyes. Or perhaps he was only nearsighted."

Immediately after I read "nearly as old" I did a double take and reread the paragraph from before. I verified that Luka was the oldest by far and I thought this was a brain fart on King's part until I read the next sentence, given it's own line--

"The list named him as Bobby Frane"

Bobby Frane, Robert Frane, RF.

Maybe this was obvious, but I love those little easter eggs and a google search didn't turn anything up so I thought I would share.
