I just finished going through all the back activity pages and found 4 S letters. Takes a few minutes to search but if you need them, give it a try. 2:48 EST
Thanks to all who sent eggs and thanks to the many of you who posted letters. My first word took me 3 days. Then I figured out I could find some of the letter in activity. Bingo! The came suddenly came alive! Thanks again for the help!
