I am driving from Seattle to Cranston RI. Does anyone know the easiest route to take for my vehicle since I will be towing. The mapquest is sending me straight east on hwy 90 and drop down through Chicago to hwy 80 and then straight to Cranston. I thought it would be an easier drive towing going south to Portland OR and taking hwy 84 straight east to hwy 80! Can anyone help me. I know there is a couple hours difference but is it worth it?
