How does Holden feel about the museum in chapter 16 of "The Catcher in the Rye"?

The museum represents childhood memories of school field trips for Holden, reminding him of a time in his life when things were simpler and when he was happier.  Allie, his younger brother, was still alive then and all in all his family was much happier as well.  More importantly, however, the museum is a place that never experiences change. This also is important to Holden because all the change he has experienced in his life has been negative: his brother Allie's death, the effects that death has had on his family and friends, the effects on his academic progress, his repeated expulsions from schools and his having to become accustomed to more new people, etc.
