Hi All,
I have spent the past few days reading through ALL the posts here. I commend you all on your insight and sleuthing! It is so fascinating to see the different perspectives! There are a couple of things that I found while reading that I wanted to clear up...not nit picking...just sharing what I know. Let's see...
Zuse--Arizona's state insect is the Two-Tailed Swallowtail and Arkansas' state insect is the honeybee. I like how you isolated facts per state!

Gman--In one of your posts you had mentioned that Ironwood is only found in the Sonoran Desert--mostly in the Ironwood...Forest. I had never thought about the Ironwood...Forest, which I did find interesting. BUT, Ironwood is found in different areas of Arizona as well. I know this because I lived in Yuma and we had Ironwoods all over the desert.

Pancho--I, like you, am only looking for "my token"--that is the token in Arizona (if there is one). If anyone has any other ideas, let me know. I guarantee if I come across any clues for other states, I will share them with the people here from those states. Just a thought...but, if you aren't going hunting for every jewel, and you have clues for other states you'll never get to...why wouldn't you want to share those clues and allow others to check them out for you? I'm rooting for people on this site to find the treasure!
Now, something that crossed my mind...it has been brought up "How would Stadther know if a token had been removed from its location?" Have you ever considered that maybe the locations of the tokens are close in proximity to where he is appearing with the jewels? That way he would be able to "check" on the tokens at least once when he was in the vicintiy. Just a thought. Since I don't know all the locations of where people are looking for tokens, I can't really verfiy if there is a Stadther appearance nearby every location...but those who have locations in mind can check them to the personal appearance schedule.
And, last thought...about the 80's. I looked up I 80 to see its route...then I got another idea. What if the 80 had to do with Intrastate routes rather than Interstate routes? Do the locations that you all are getting have a state route 80 nearby?
Don't know if any of this helps, but I want to do my part in sharing what I have with you since what you've shared has helped me. And, for what it's worth...I think the book contains a wonderful story. My children and I listened to it in the car during a recent trip...and they enjoyed every part of it! I haven't seen them so enthusiastic about a book and sharing it with others. Having read A LOT of children's books, I think this is a great book because it looks to involve the whole family in an activity--now how many books do that?
I don't know who wrote it but our Pook also has the letters MYMRLYVR on the tag...so it seems the letters are the same on each one. I haven't figured it out, but do these letters correspond with anything you all have found?
Thumbs up all!! I enjoy reading everyone's thoughts!
