Way cool!
Neither of my kids are particularly interested in climbing but I take them and their friends top-roping periodically and everybody always has fun. On one hand I'm jealous that we don't have those kind of common interests but then again, you can't force people to be who they're not, just give them the opportunities to decide that for themselves. Similarly, I don't play in the band that's currently shaking house off its foundation. We all still enjoy spending time together which is what counts most.
And they get some great genes from their mother who is as big a kid as I am. She doesn't climb often or hard but she's happy to hang out with me on a windy ledge with a good view every now and then. Mostly I'm happy that she's a glass-half-full kind of girl who doesn't consider sleeping on top of a Jeep, with a terminally broken engine, in the parking lot of a Jeep dealer, in a different country to the one we started in, anything to worry about!
I think the only sport that I wont encourage my kids to do is whitewater kayak, I have been boating for decades and have always felt that kayaking is much more dangerous and risky than climbing or back country skiing.
+1 although I didn't need to make that decision myself; their mom exercised her veto rights before I had the chance to suggest it!
