Lori,
I hear you say you don't want blood specifically for Curt. I don't know
the situation with your bloodbank.  I do know when I had my knee surgery
that the cost of the blood would have been a sizeable out-of-pocket
expense for me had I not self-donated in advance.  Insurance covered only
administering a transfusion, not the blood itself. Maybe your plan is
different.

When my mother had her kidney transplants in the 60s, they got lots of
press.  She had O- & they had to keep flying it in.  I was too young to
donate.  To our surprise, a union & all sorts of groups donated for her.
We weren't affiliated with the donor groups in any way. If Curt needs
donors, you might try any professional/trade associations he may be part
of or fellow employees.

We've found that people want to help.

Our blood bank here has ongoing drives.  Most companies bring them into
the office 1-2X/yr for employees to donate, & a mobile bank has regular
daily stops throughout the area.  If your community lacks that, you might
want to see about getting a program started.

I'm seeing this is a very tough time for you, so you might need to put
those ideas on hold while you deal with your very full plate, for now.  

Hugs,
Fig
