This is Cultus lake water park. I have to remember not to go here on a cold or cloudy day.

That's everybody packed in the hot tub.
The slides are fun, the tubing, the valley of fear, the tall crazy slides. But when you're wet and it's cold then you can't really enjoy the rides without shivering and heading for something warm like the hot tub or a towel.
On the plus side, the line-ups are shorter. And besides the slides there's always picnics.
