I'm going to be taking a cross-country trip soon, from West coast to East, and I'm curious about good camp sites and eateries and other such things along the way. Below I've sketched out some general points we'll be stopping off at, any tips would be helpful....

OK,

Spokane to Missoula (via Northern Idaho).
Through Montana & North Dakota on I-94 all the way to Fargo.
From Fargo to Duluth via US-10 & 210.
From Duluth to Sault Ste. Marie on the Upper Peninsula..
Cross over into Canada, take the one road in the whole country (trans-Canada?) to Ottawa and Montreal.
Take I-89 South and make a bee-line for Boston.

Questions:

What the best campgrounds in the Missoula area? Without RVs? Here's a list I'm looking at. Any good food in Missoula?

Doubt we'll stop in North Dakota, but what good campgrounds are there in the North Woods and the northern coast of Wisconsin? Any towns with really good food?

I hear the Upper Peninsula is just a big wilderness. Any pointers?

Thanks ahead.
