We would love some tips on taking a road trip between DC and Park City, Utah this August with our kids, who are ages 8 and 10. We would like to take 3 days to get to Park City and maybe 5 days on the way back (we will stay in Park City for about 10 days in between). We are outdoorsy people who love to hike and enjoy nature; we do not like anything too touristy. We also like to stay in nice places; no strange B&Bs. :-)
Any advice would be appreciated - Where should we stop? What should we see? Where should we stay? What routes should we take?
