Isn't there a nice looking, new yellow tandem axle trailer sitting around up there? You could have just hooked on to it, and had him pick it up sometime this winter, when we have acceptable weather.
Were they out of old tires up there too? I've taken to hauling engines in a old tire after someone suggested it to me. It seems like blocks always walk out on me, even if I spend a hour screwing them all together and cross tying them. Last two I hauled I just threw them on a old tire, and one strap across them, and let them ride, except for the 6v92 I brought home a while back, it had a allison on it, and those have a nice flat pan to hold them upright.
