I was in a hurry earlier, so thanks for bringing this up.
I've seen a BUNCH of applicants who were VERY non-traditional, screwed up in undergrad, came back and proved themselves in a post-bac or second Bachelor's program, but still had a subpar GPA (b/c of so many hours accumulated with a crappy GPA), had great EC's/life experiences, and got into one or several DO schools. These same applicants got no love from MD schools, and many have gone on to rock med school and the boards.
My point is that DO schools can be very forgiving, and have passed on many squeaky clean applicants in favor of those who know what they want and have great and varied experiences and backgrounds to bring to the table.
