I'm on Wolves of the Calla now, just beginning. I think the books are great. I especially like the little ways Stephen King alludes to other books and stories. I can't wait to get through the next ones. This certainly was King's Magnum Opus.
I would love to hear where people found King's references, because I'm sure I've missed some. I have read the "family tree" of SK books, but was wondering specifically where things were found and if there are smaller things thrown in here and there. I guess they should be spoilers so I'll start:
Gunslinger:

The Waste Lands:

Talitha is too close to Tabitha (his wife)
