What a fabulous trip you seem to be planning!! I'd invite you to my school, but it doesn't sound like we're on your travel agenda. I'm in San Antonio, TX. I hope you'll get lots of offers to visit.
Do you know the Sisters are coming to Australia next July? It's at a reading conference, and I can get you the info if you are interested.
Also, are you a Facebook fan? Do you know about the SA Daily 5 page which is a site started by teachers across Australia? Others can join, too (I did), but it's full of ideas from teachers like you who are sharing great ideas. You should check it out!!
Have fun planning your trip, and I hope you get lots of offers to visit here in the States.
