Can you swim in the Hudson Bay?
"Depends on what you define swimming as."
"Yes, you can swim in the Hudson Bay, but you'll freeze."
and so on.
What I'm asking is if it's practical enough to swim in it to where some people actually do it. A friend who's from MN said that few people swim in Lake Superior even in summer because the water is always cold. So I imagine the Hudson Bay would be worse?
