Just for those curious, you CAN get dirt shipped in very big plastic/kevlar bags that are strapped to pallets. This is similar to the way certain heavy (coffee being one that is just starting to move to this) food shipments are being handled. Of course, it does require a heavy loader, flat bed, straps for the flat bed, and roads improved enough (and all year enough if its not summer and dry) to get your shipment to you. These bags can even be air lifted by CH-47 helicopter (I believe it can carry up to 2 of them, but I'm not well versed in this method of transport). These are not the 10-20-40lb bags of toil soil you see for sale at the lawn and garden shop (although the larger plastic bags could just as easily be stuffed with them, and those 10-20-40lb bags can be wrapped on pallets and shipped as well.
The shipping will cost a lot more than buying local, but you will still pay shipping then too, and still need loading equipment.
I've often wondered how northern Canadians tough it out when it melts and during the very heavy drifts when its hard to get supplies in. The latter is probably easier to deal with than the mud though!
