Hm, I'm not sure if there's a Macy's around here or not - I know of one almost an hour away... I might just make a trip to the po and let them drop the letters into the big blue box out front! lol I mailed a package once, and they were fascinated with it - so I had to explain that when you drop it in, someone picks it up for you and takes it right to the person you're sending it to, I think they'd even get a kick out of that, mailing their own letter. They are definately easily amused LOL.
That is so cool that some of you get letters back from santa!!
I know a girl who makes some up and mails them out, I may have her do some for me, the girls would love that I think.
