Do they celebrate this holiday where you are stationed(if you are overseas)? What about Thanksgiving?

In Australia because the town has a very big American population they do Halloween here. Its kind of funny because you know what neighborhoods to go to(the ones with the most base houses). Most Australians take part in it with their children but only a few hand out candy. You have to buy the costumes online as there is only one store here who sells them year round. No one gets them in just for the holiday.

As for Thanksgiving we all get together and do it as a potluck a few days before, or you get invited to someone's house. We do it at home as a family also. Australians do not celebrate this Holiday though. I invite all my Aussie friends when we do it, they love an excuse to eat, have a drink and be merry LOL
