Just signed up. Planning on taking a road trip in June 2015. My son and I plan on taking about a 3000 mile trip. We'd like to do it in 3 weeks. But we'd also like to be able to make some stops and stay awhile. How many miles is "normal" to drive each day? I'm 65 and my son is 21 so we have different ideas on how much driving per day is ideal :). Any suggestions? Thank you.
