How Come I've Never Seen This?

Here is a link to a strange snow phenomenum that I've never seen before. Click on the post title to get to the BBC story about snow rolls. Wind blew the snow into these rolls and pushed them into larger and larger rolls until they got too heavy to push or reached a fence post or other obstacle. How come that never happens here? I've never heard of such a thing. We sure got plenty of snow and plenty of wind and plenty of empty fields.
