Where can I find that in the Missal?

As we continue to become familiar with the new translation and layout of the Roman Missal we are discovering that some things are not in the places we have come to expect them. 

For example, many of the date or feast specific prefaces are found with the other presidential prayers for that Mass.

Today a pastor called wondering about where to find the Sprinkling Rite which can replace the Penitential Rite.  It is found in an appendix in the back of the Missal beginning at page 1453.  (Isn't it nice to have the pages match in all of the editions of the Missal?)
