My brother just sent this to me and . . . all I can say is that cold weather seems to do really crazy shit to Canadians. Seriously, this guy spends almost a decade excavating his basement using remote control dump trucks and loaders at a rate of only eight cubic feet per year. The article has a lot more videos on it, but there are a few interesting ones, below. They also did a more detailed posting about him which includes some stunning photographs.
This makes me think my childhood idea of having a massive train track that goes all over my entire house - in and out of walls and all around things - less crazy. Or my idea of having one of those hamster habitrail things, but like all over the house and yard for like a mile. Okay, maybe that is kind of nuts, still.
