We all known someone who has been touched by cancer. While the ISI is frivolous, we like to do some good. So please, in lieu of a sign up fee, please consider donating to the American Cancer Society through this page. 100% of your contributions go to the ACS. Last year we raised $480! This year, we've set our sights even higher. Suggested donations from participants are $25. Thanks! If you're not "competing" in this event, and are just a charitable person, thank you, as well. There are many good causes out there, and we're grateful you helped with this one.
