Not to trump you, Wil, but I want the ALS Association to get picked so much so that I want to point out that they also have opportunites to sponsor teams in their 'Walk to D'Feet ALS' which they hold yearly.
Our company participated last year, in honor of my coworkers husband, who suffers from ALS.
Details here of last year's walk here:
