Just got an e-mail in from Snowball (Sheila) sending a photo she wanted me to post for her on the Forum
She is in Idaho at the Upper Coffeepot Campground...about 25 miles south of West Yellowstone, and two miles from Macks Inn.... She was just certain you'd know right where Macks Inn is!!! 
It is Memorial Day weekend, and they are getting snow!! This photo is taken from her large rear window in their fiver.... Enjoy!!

Mission accomplished!! Have a wonderful holiday weekend!
Happy RVing!
