Went through a bad thunderstorm with big hail at Half Moon campground north of Big Timber WY, in the Gallatin National Forest. The lightning was amazing and the thunder was deafening as it echoed in the canyon. We kept hearing a big roaring sound beforehand and finally figured out it was the waterfall 1/2 mile upstream, as the storm moved through it. That water quickly appeared in the campground, and I was glad to be in a higher-level site.
Not so much wind but torrential rain and hail.
We were in a Cabela's Alaskan Guide tent and it did not leak a drop.
