My daughter and her new husband are taking her new car from Chicago to is post in Tacoma, Washington. They have from 5 to 7 days. He has mad the trip once across I 90 and feels that it may not be interesting enough or safe enough this time of year. So he is considering taking I 80 across to California then taking I 5 up through California through Oregon and up to Tacoma. My guess is that this last part will be particularly nice if they take time to get off the road on the way. I have a few questions. Is this a good route given the time that they have? Is it safe for travel in February? Are there interesting things to see on the way? I know they'll miss Mt. Rushmore but is the trade off worth it? Looking forward to comments they are looking to leave on March 1. Thanks for your help.
