Driving cross country from eastern PA. From Brainard Minnesota we catch I 94 across North Dakota and then link with I 90 in Montana and take that into Coeur d'Alenem, ID. Any suggestions for lunches or for dinners as we trek across? We don't want to get too far off the highway, but don't have Jim Leff's constraints of 1/4 mile. Any recommendations would be appreciated. Thanks.
