How much is your life worth, Ozebee? Is it over tram or train tracks? Either find an orphan or train surfer whom no one will miss to do the job, or tell the caller they will need to hire a pest control company which has climbing gear and good life insurance. Or else tell them to set up a viewing platform as a tourist attraction, and sell the honey for top dollar as "City Gold".
Seriously, you have to know your limitations! Have you made a decision yet or attempted flying up there? By the way, do any swarm collectors have insurance of any kind?
