I've been donating blood with this group when they travel to Yuma on and off for about 5 years.
Today, I signed up and did the questionnaire online. They were set up at Foothills Library.
The nurses were health concious, couteous and respectful; they had a nice rapport with each other, probably from traveling all over AZ with the bloodmobile. The room where everything happens had a confortable ac temperture to go with the cleanilness and the music playing overhead. The donation went well, and they watched us donaters as we sat eating chips and hydrating to make sure we were okay.
I wish I could Yelp on the library, but didn't have time to look around as I had to leave.
The donation website is pretty cool; it gives your chloresterol count, it tracks and adds up bonus points each time you donate, etc etc. It's a good deal.
Not everyone is eligible (or wants to) donate blood and I get that; but if you can and are able to, why not? Just saying.
