THEN DON'T WATCH THIS!! You think the first bit is bad, but then there's ANOTHER 60 feet to the top, outside it hand over hand. !!!!!!

My nuts shrunk into my lower body and I had to hang on to the arms on my chair as I felt myself slipping forwards. 
It's only to change a flashing beacon.........done loads. :/
Heh.............only. 
My mango tree started fruiting this year, after years of inactivity. But then the ants, the bats and the humidity started posing a threat, just as the bastards were ripening. So I had to clamber up the ladder, top step and all, then onto a branch and use a mop handle with a plastic container affixed atop to lift and twist the fruit. Great crop. Mangoes daily now. No fear.
Stay, lords and gentlemen, and pluck no more,
To pluck down justice from your awful bench,
May rather pluck on laughter than revenge,
Pluck them asunder,
The ripest fruit first falls, and so doth he,
Who dareth not ascend to ladder acme.
