I'm re-reading It for the first time in 25 years, and I read 11 /22/63 during the first quarter of 2012 , then covered the DT series over spring and summer. I really enjoy the connections. So far in It, I have noted "

the voice of the turtle", "a universe where roses sing", and "wheels of destiny", and "wheels of the universe"
in the re-read. Lots of little notes here and there.
