I dislike REBUILDING fences.. so much work and it looks pretty much the same when you're done.. especially barbed wire. I'm slowly changing over to high tensile, needs better anchors, but so much easier to keep tight and electrify as well.
Irrigation is one of the necessary evils around here... spend 2-3 hours a day walking back and forth, there are things I'd rather do, but it's not too bad.
I like anything to do with cows.. OK, reaching in for retained placenta and backwards calves isn't pleasurable, but it's not frequent either... and I think everyone will agree there's no better sight or feeling than when that newborn calf shakes the goop out of his floppy wet ears and wrinkles his nose!
I don't mind working on or with equipment, I'm pretty good at it as well, and I always like making stuff work better than the engineers who never had to use it did.. Stacker wagons, etc. Recently I've picked up chainsaw rebuilding and tuning, Next on my list of things to make (with a friend) is a alaskan mill.
I LOATHE PAPERWORK!
