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. Suggested donations from participants are $25. Considering this year is ISI XX, we’re trying to double last year’s total of $400. 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.
