Damn right! I turn my trips like Disney into science time. Once in a while, we discuss the "simple machines", sometimes it's hydraulics, and other times we discuss social sciences, crowd interaction, etc.
I hardly go anywhere with my babies that isn't more educational than a classroom. Even when we screw around at the beach or fishing, it's marine biology time. And when we get home, we look up all the questions I didn't know the answer to. We have fun, and we all learn lots.
I lived in Virginia till I was 17 and would go surfing practically every day after I was done with my studies. I learned amazing amounts of stuff from meteorology and marine biology. There was also colonial Williamsburg, Nauticus, Navy Norfolk, Yorktown, civil war battlefields, Roanoke island down in the outer banks etc. etc. All of which I spent many many a day at in my home schooling career. All things I could never of possibly been able to do if I was in public school because I would be stuck in a class room.
