had this to say:

We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember Timothy Murphy
saying something like:

Anyone got advice on clearing vegetation from very high gutters?
Is there any kind of robot that goes round gutters cleaning them?
Or anything else short of hiring a "cherry picker"?

A long pole with a hooked-over profiled scraper.

An angle grinder.
