Oh don't let that stop you!
We have an Australian partner this year but not a European one, but we hope to next year. And we know it's a burden for our members outside the US, so if you want to mail yours all at the end of the month, that's totally fine. It doesn't matter when they get to MD Anderson - they come in for months after the challenge and brighten people's day!
The idea is to play, and have fun, and do what you can. If you have a local breast cancer center you can send them there as well.
But either way, stay and play!
