Stocking up on food

So we're in Missoula now getting some rest and stocking up on more provisions for the 175 miles to Great Falls. Lots of doggie treats and kibble are needed, as well as more stuff for me to eat. Luckily, there's a Dollar Tree here.
We're camping at the KOA on the north side of the Bitterroot River. It's a lovely place with its wood swinging chairs and gazebos. There are even some quaint cabins available if tenting isn't your style.
The proprietor, Smokey, says that when the grounds were established some forty years ago, Reserve Street (that's what you'll take from the city center) was just a dirt road. Now this whole place has been swallowed up by 'suburban sprawl.' Still, it maintains much of its charm.
I've done most of my washing, and the dog has just enjoyed a chicken and potato salad picnic with me. Nothing to do now but build a fire and hope these clouds blow off so we can watch some stars under Montana's legendary wide skies.
