If that link doesn't work for you, you can go to http://www.aidswalk.net/sanfran/ and click on "Sponsor a Walker" on the left hand side. Type in my first and last name and Viola!
Even if you don't know someone who has AIDS or HIV, given that statistics currently state that 1 in 4 people who have AIDS don't even know it themselves. I'm not going to give lots of numbers, or statistics that might be out of date, or other fairly pointless data. I am going to just ask you to keep this in mind over the next week. If you find that you have an extra $1, $10, $100, whatever. Help a good cause.
