I have a friend with Crohn’s. It’s a bad disease.
From Jeremy Twigg via email:
… This September, 16-year-old Clinton Shard of Squamish, B.C. is climbing Mount Kilimanjaro as a part of a team of six people led by Crohn’s patient Rob Hill, who is the founder of the Intestinal Disease Education and Awareness Society, or I.D.E.A.S. Both of these adventurers have Crohn’s disease, and have overcome tremendous obstacles in order to be able to take on this challenge.
While they are on their journey, they will be posting updates on Twitter (#roberthillclimb, #weneedideas); blogging, posting photos and videos (IBDAdventures.com); and even answering questions via video from their fans on the web while they are climbing! …
Check out their IBD Adventures website.
I’ve subscribed to the blog.
Good luck to all.

I too have a good friend with Crohn’s disease. It certainly makes life difficult. I will definitely be checkin in on this.
