Planning to drive from LA, CA up to Idaho for a 10 day total vacation-Family of 6-kids ages 16 to 22. Mid June or Late July. Would appreciate any kind of itinerary help. Enjoy hiking, adventure, rafting, horseback riding, fun interesting things, great food, reasonably nice hotels but have to keep an eye on the budget. Any great values in activities or hotels/resorts would be appreciated. Thanks tons!
