    I'm thinking about purchasing my first new truck.

    Hi. I have always bought used trucks for my company. (I've also never bought a new car or pickup truck for my family, so I am new to this). Last year, I had mechanics and towing costs that amounted to more than 5% of gross revenue. It was a set of particularly costly repairs, and not a typical...

    Zip line brake

    I am installing a couple of zip lines up at our cabin. Not terribly steep, (maybe a grade of 5%). I'm making two of these: https://www.ropescoursewarehouse.com/Catalog1/advancedwebpage.aspx?cg=181&cd=3&LastStraightCategory=Zip%20Trolleys%20Accessories&SBCatPage= They are designed to work...

    Bee hive relocation

    After about 3 weeks of trying to time this removal for a cold enough day, but having snow on the roads every time, we finally just timed it for the warmest day in about a month. So, my wife's bee keeper's suit was necessary...

    Score sheet, and this summer's ITCC

    Score sheet, and this summer\'s ITCC Not to belabor it, but rope angle potentially impacts scoring 3 ways. Each of the following gets 0 to 10 points: A) "Use of safety procedures, equipment and always secure against falling"; B) "Rope control and use, no struggle" and C) "Tie-in point or...

    Estimating branch weight when leafy

    I like to work my way up, starting with smaller picks, working toward big ones, and homing in on the weights of branches that way. But I was thinking of a way to better estimate weight (of leafy branches) early, and this occured to me. On most branches, the center of gravity resides at a point...

    Women getting cars stuck

    I have stumbled onto a website that provides endless videos of models getting cars stuck in fields. Also, trying to start cars with dying batteries. The latter genre shows a particular interest in their feet and footware, as they pump the gas. Not a porn site (at least, not in the public...

    Squirrel High Dive

    I've had many encounters with our fuzzy little branch-stripping friends, but never had one launch off my shoulder until today. It jumped out of its hole, landed for about a second, then sprang out and down about 25 feet into the snow. Babies fared much worse...

    Speedline retrieval in a tree with wide spread

    We're due to remove a large hybrid ("Siouxland") Cottonwood in the next week or so, and it has one good anchor point for a speedline over a house out to another tree by the street. Lots of brush and wood, so we'e like to use it. In other trees, I've been able to pull the speed line down to...

    Rockie Mountain Results

    First, the results; a couple of opinions to follow. Once again, Charlie Wagner will be representing us at the ITCC. He won a very competitive Masters, after winning all events but the throw line. (He accomplished this despite the fact that he was coming back from being sick, and operating on...
