I ain't lost

I'm hoping some of our super-expert backcountry skiers can weigh in on this: How do you negate the crevasse danger while skiing glaciers? I've spent my entire life learning the "ropes", how to climb and travel on glaciers, and although we all take educated chances occasionally, the basic rule is never travel crevassed glaciers unroped. Now, almost without exception, every posted photo I see of experts sking the glaciers, shows 'em unroped. Are you just counting on the weight distribution on skis to keep you out of the hidden ones? Are you crazy? I ask becuz, like a lot of climbers who also ski, I also blunder across glaciers on spring ski-mountaineering trips, hoping my experience will help me "read" the glacier and avoid trouble. But that's gotta be somewhat dillusional. Watchy'all think?
