Hey Moserkr, I'll be doing the same, walking that line, and looking for a resident guide before then. I haven't found it yet, but there ought to be posts in FB or Craigslist, etc, of WY resident guides looking to share the adventure.
It's sad.
Stan Mills on youtube hikes among the Yellowstone grizzlies on purpose. Worthwhile watching a few to learn about grizz behaviour and where they are likely to be found or not. He hikes without a gun.
No pictures, but smoked Venison backstrap steaks for an hour today and then moved it the frying pan for a quick finish in butter and pepper! Perfect every time.
