Calexico to Idaho Falls ID
I am planning a trip to Idaho Falls Idaho late September. I don't usually go that far north in September October, but I'm attending a wedding so this is special. I hope I don't get caught in an early snow storm. Google says I-15 is shortest and I am not interested in scenery or tourist stuff I just want the shortest run and less hills the better my rig is older and I don't care to strain her on long steep hills. I'll be towing a GEO tracker too.
I just want to get there attend the wedding and get out before the snow flies.
Any ideas for a better route ?
