Jack, for your friend with the 3 kids, not all is hopeless.
I started with a 'dealbreaker' wife and slugging 3 young kids by myself to the hills (at the time I did not snowboard).
Now that they are good enough to get up the chairs on their own, it's a breeze. Plus if we all go, my wife would be left out, so now she is starting to come along, actually liking it. She's the one pushing for a family pass this year. I am sure not complaining!
Sure, a non skier/boarder spouse makes it more challenging, but you usually don't marry Mr. or Mrs. Perfect. Life together is a road, and can be full of detours and surprises. That's what happens when you have a ring around your finger.
