It's not just where you go, but how you get there...
We will be driving up to the mountains for some summer fishing, camping, and hiking.
My father (and his father before him) was a teacher, which allowed us the luxury of (mostly) free summers - and we would take a summer drive every year. Many times we'd go across the country to visit family in other areas. We'd usually take a different route and by age 15 I'd gotten to nearly every state. I remember the trips with 5-7 of us in a VW Westy; everything from tired cramped travelling on stretches of road that went forever, to "moment" views that could make JMuir, himself, stop in awe.
While the kids are young we are trying to do the same thing and expose them to more than just the southern California lights. Wishing you luck in getting to do the same, kimosabe.
