Do We Take Our Children too Many Places?

Sitting around with a group of friends last night at bookclub, we began talking about how often we take our kids to the museum center, the zoo, and parks all around town. Nearly everyone had memberships to several kid-oirented places. We agreed that part of the rushing and running was because we didn't always want to be in the house with kids, but it did make me question the sanity of the excessive trips. Would any outings seem special if they got to do them all the time?
Do we take our children too many places? I thought of my own childhood where I can remember specifically the times we went to a waterpark (the Wally-World experience with Aunt Mary, how could I ever forget it), or to a park for a company picnic or post-season team celebration. I remember standing in line at the World of Wheels carshow to get the autograph of Chachee from Happy Days. But what I mostly remember about my childhood is riding my bike to the library, spending hours reading, playing outside with neighbors or siblings, and making up our own games (like "let's throw our flip flops onto the roof of school 61").
So I'm not sure where this constant urge to never let my children have a dull moment comes from. I think like many parents in today's culture, I just want my kids to have a fun childhood. In the midst of so much pain and turmoil in the world, I want to create this environment where their lives are untouched by suffering, maybe even the suffering of boredom. Yet, I think it's those moments of simple, childhood wondering and thinking, that our kids might be missing the most. It's not like my children are constantly asking me to take them places, it's my impulse to entertain; I want them to remember going to cool places, and getting to pet iguanas, climb rock walls, and explore nature.
But maybe none of these events will stand out for them because there were so many parks and places too often. Somebody's probably written a book about this already.
I do wonder, though, if that World of Wheels show is still around. Maybe I should take my kids....
