You don't need a tan in a cold climate. Get as much sun as you can, take vit D if you're deficient and don't worry. If your body needs protection from UV rays, it'll tan. If not, it won't.
Besides, getting a tan in a cold climate can INHIBIT vit D absorption. High-melanin skin is less efficient at making vit D3 from sunlight (I can't remember why, just that more melanin = greater chance of D3 deficiency in the North -- and I assume far South too). Think about it: if you live on the equator you need better protection from sunburn and skin cancer (more melanin) and you don't need to get as much sunlight to make vit D (as there's more sun). It's why a number of drs have suggested that some ethnicities should be recommended to take D3 pills once they're living a certain distance from the equator (especially expecting mothers and the elderly). If you want your D3 to come as naturally as possible in a cold climate: let your skin go as pale as it likes. Then supplement when you get low.

I rarely talk to people about Paleo/Primal, but, when I do, it's when they're NOT complaining about their weight or health.
You see, I don't really "do" pity. And one thing I've learned about people is that they're more open to suggestion when they're happy and stable. When they complain they only ever want pity, not to be advised.
