Lurking the thread.
We used to take the kids up to Kenosha pass every year, hike in and build Quinzies and prep, then go sledding during the afternoon and spend the night.
Always told them to stomp down their quinzee area first before piling up snow. Sure enough, they didn't one time and had to sleep 5 of them in a little quinzee built around a stump they found after they dug it out.
