In Alberta we have West Edmonton mall. It's supposed to be the largest in the world. It has a pool that surrounds their underwater park complete with sealions & saltwater fish, turtles ect. I was wondering if a pool like that has as many or more issues as being in OW lake location, could a dive shop open & train divers year round for OW without going outside. It's around 24ft deep & used to have submarine tours in it. I would say it's around the same size as a small lake in Banff national park where they teach OW. I have dove it before & it took 45 mins to complete 1 lap at a slow pace.
