I don't put my local in my profile as I don't want a bunch of info out there really but then most TC people know where I'm from.
A fun assignment might be to go to a international grocery store and find some different ingredient that that culture cooks with and show at class, could be extra credit for students.
If nothing else you will get students to experience these cool stores and find new things in the world.
Or feel the hate of a store owner that hopes you are not INS or the health department and just wants you to leave and never come back.
You know the Mr. tiki thing may help your students with this as well.
This will teach them at times the international mail sucks, and at times irresponsible people can suck.
