I apologize if I'm repeating a thread... but my neighborhood's dsl has been down for a few days and I'm running on 56k temporarily

I'm in Lake Tahoe until next year and there's some heavy storms developing soon and will be purchasing some chains. Now I've always been curious... for AWD cars like ours.. do we put chains on the front or rear?

I might also add that I'm running on 20's staggered. Since I'm already in Lake Tahoe there's no steep roads, but I still want to be safe and put chains on driving around town.
