B,
You are truly my hero. After reading all that you have been through in your life with your health, and you can still find the inspiration to set a goal with the walking, I really admire that. I use to be a walker too. I started in high school and I would leave home at 6:00am so that I could walk to school instead of taking the bus. I have always enjoyed the solitude of walking. I am now burden with Arthritis in both knees and not able to walk long distances any more. If I would be granted one wish, it would be to be able to walk again....that is what I long for. God Bless you on your journey and I will keep you in my prayers that you are able to reach your goal.
