So, I am chatting with Lance. He spoke to Josh's nurse. He is already in Texas. If you want to send mail or parcel only, here is his contact info.
Brook Army Medical Center
3851 Roger Brook Dr.
Ft. Sam Houston, TX
78234-6200
ATTN: 2 South / SPC Joshua Boyd
Keep in mind, according to his nurse, he will not be able to speak for "weeks to months."
EDITED TO ADD: He is in surgery right now... 11am. I will post as soon as he is out and I know more.
Please send personalized things if you knew him. This is the most sensitive and delicate time in recovery and it will help him a lot.
