Huge kudos on conquering the foot-over-foot down the stairs! It really is an exciting and major milestone, even with a Vulcan death-grip on the railings! As other have stated, I have some days when that's a fairly easy feat, and others....not so much. When it isn't easy, I revert to backwards stairs and that's ok because you don't want to push yourself down with pain or bad form.
What a lovely setting for ice and elevation! I can't believe you drove for 4 hours; yikes! Have a blast with your reunion friends, and hey, it's good medicine, lol.
