The first pic is from one of our trips to the Rockies in 2008. The second was taken last week.
For me, backpacking with MS isn't a whole lot different from backpacking before I had MS and/or before I learned I had MS. I actively work to stay cooler, now, and also try not to overdo it out there. But I did overdo it some on this most recent trip, and I enjoyed both pushing it and that utter sense of exhaustion.
In my mind, there's something new about backpacking with MS: It's a persistent sense of gratefulness as I walk through those hills knowing that I have (so far; knock on wood) been incredibly fortunate to have the level of mobility that I do. Knowing that every step may be my last, as is true for everyone, I walk with immense satisfaction in the backcountry.
