Some people are completely crazy and I think that these qualify to be in that category. I have jumped into a pool that was about 50 degrees once and thought I was going to die. This is shear lunacy. Looks like a bunch of drunk people who obviously didn't want to be drunk anymore. They have meetings for that, no need to jump into near freezing waters. But, hey what ever floats your boat, or I guess your bear. I can't see myself ever doing this, but hey, never say never.
