Update: I'm sending out another package, so I had Caitlin ask more of her friends/coworkers what they might like. She gave me a few more ideas. I updated post #22 and added her friend's requests, in case anyone is looking for more ideas.
Several people expressed that they would like my daughter's address, once she was deployed.
I'm happy to report that she got to Afghanistan safely. Got stuck in Kyrgyzstan for a bit, but bummed a ride on a C-17 and finally made it.
She's busy working and making friends already.
Rather than post her address publicly, I'll send it out by PM. If you would like it, just let me know or shoot me a PM.
If you're planning to mail stuff, know that it is very much appreciated. Very much appreciated. Whatever she receives, I know she will also share with her fellow Airman. Unfortunately, not everyone over there has such wonderful and loving support as this.
Keep in mind that there are prohibited items that cannot be sent.
This is a pretty good site highlighting the basics. I think there's a more comprehensive list on the USPS site.
Thanks, everyone!
