Well I can’t say I understand the appeal of collecting insulators, but I’m completely in love with the idea that there are people who enjoy such a niche hobby with such intensity, and apparently have been enjoying it for decades, and have societies and conventions and everything. Unbelievable. This is what the internet is for.

If you're interested in insulators you may also be interested in the telegraph poles that they're mounted on, for which we have the Telegraph Pole Appreciation Society, https://www.telegraphpoleappreciationsociety.org/. Do sign up, it's only UKP 10 for lifetime memebership.
