About 30 years ago, I hired a high climber to limb up some fir trees around my house, to let in more sunlight.
After watching him, I bought my own climbing gear. Spurs, safety belt with chain, etc.
I cut limbs from about 150 more fir trees on my property.
It gets exciting being up a tree, 90 feet in the air, and you're at about 8 inches diameter of a tree that starts at over two feet on the butt.
When you get a little breeze, you can rock back and forth about six feet. Quite a "ride" (GRIN!)
As I got older (64 now) my Wife told me I was getting too old to climb trees. She worried about me having heart problems up there, and no way to get me down.
