Have read bunch of good posts and answers from this forum, which helps a lot for my coming summer trip planning: from Detroit, MI to San Francisco, CA in July. Looking forward to driving 6 to 8 hours per day (rest time is extra), mainly taking I-80 and I-90. MS s&t shows me that 500 to 600miles for 8 hours (9am to 5pm).
So, could someone has the experience let me know if it is reasonable? If not, how about 400 miles per day?
