Well, that's a good idea.
I get the feeling like there are people in different parts of the country who read this. I would love to have postcards for my students from each of the states we visit. I already have 25 from my mom (Michigan). If you have the time and inclination to be a part of my classroom and my students' learning, I would need 25 postcards, so I'd have enough for each. My students use the postcards at the end of each unit to comment on what they learned. They write them in their free time and put it in my mailbox outside of my classroom. Email me at rosynic@yahoo.com if you'd like to contribute...and I can pay you back with my wonderful ECM funding, just send me a bill!
