From Friend of the Group Hemant Mehta:
I'd like to bring together a bunch of skeptics/atheists to raise money for the Leukemia & Lymphoma Society. I'm hosting a group for the Light the Night walk and I'd love for Chicago Skeptics to join me. All the information is in the link below and you can join the Chicago group by going here: (http://pages.lightthenight.org/il/ChicagoL12/FoundationBeyondBelief)
Hope you'll join me!
Even though this is put under the rubric of 'atheists' raising the money, it his seems like an interteresting thing to do even if you're not an atheist (not all of us are), a true showing that nonbelievers and believers can come together for a common rationally and scientifically useful cause.
RSVPs are turned off on this page, as I wan't to encourage you to go to Hemant's page directly. But if you plan to participate, leave it in the comments.
