Just June bug-
The Breast Cancer 3 Day site is
www.the3day.org (that is the 3 day/60 mile one)
I found that the fundraising wasn't nearly as bad as I had originally thought. My friends, family and local community all were supportive. Also the 3 day has message boards with a fundraising discussion so you can expand how you fundraise and also get ideas to try (garage sales, craft shows, etc.)
I hope this helps.
