No point doing this the hard way! Glen, a local sawmill operator stopped over the other day to talk about some lumber he will be milling for me this summer. I was just about ready to start cutting out the railroad rails when he offered up his boom truck to pluck them out whole (in exchange for me giving him the rails for his sawmill operation). Sounded like a fair trade, so he came back a couple days later after I had removed the hayloft floor and we got them out in a couple hours' time.
I was a little sad as the rails were loaded on his truck, thinking of various ways I could incorporate the rails into the renovated barn if they were still ours. But at least they will get put to good use this way, and the job is done.
