Keep your eyes on local Palo Alto MedBlogger Dr. Enoch Choi as he heads down South to volunteer for a couple of weeks. I know at least one other blogger who did a stint volunteering down there, and getting their firs hand reports is eye-opening. You think because you see the same 10 clips of footage over and over that you have a picture of what's going on, but it's the tip of the iceberg.
Good luck Enoch! Keep us posted.
