Something I forgot to mention in my wrap-up was our experience not renting a car. To review, we used DME to get from the airport to AKV and We-go-shop to have groceries delivered. On several occasions we didn't want to wait for the bus, usually because it was just too darn cold. Our experience with the bus to and from AKV was almost always very good. I think we usually waited no more than about 10 minutes for a bus.
All in all I think that we spent about $90 on taxis and if I guess correctly about $30 on the groceries above and beyond the cost of the groceries themselves. So I'm guessing we spent total $120 because we didn't have a car.
My feeling is that for us renting a car isn't necessary and we'll probably not do so in the future.
