My wife can't and won't ski. She has genuine medical issues that are valid excuses not to try, but I doubt she would enjoy it as much as I do even if she could. This works out on family trips though because the kids can't hang for more than a couple hours so it is best to have a "lodge mom". to take over supervision duties so I can get some serious laps in later in the day. It's also nice because when I choose to go solo she acts relieved instead of jealous. She'd rather stay home with the kis than ride along and sit in the lodge all day. But if we're going for a weekend or longer then she can find other stuff to do. Last time we actually took two cars. Next year we may venture to a place like 7 Springs with lots of other activity options.
My wife used to ski, back before we married. We had a lot of fun trips together. Now her health prevents her from skiing, but she supports me in my skiing, especially if I take one of our grown kids along. Sometimes she tags along and reads a book in the lodge. Without the health issues, she'd be up there with me.
