Funny old whole damn world, innit?
One minute I'm posting about a bloke with an overgrown garden, the next I've let GE gently waft a few miles and suddenly, I stumble upon the letter that has eluded me the longest!
It's near Plymouth, and it's a zig-zagging path (that should of course be nig-nagging) up a steep bank.
So that's the full set of 26 upper case letters. I need to go back and find better examples of a couple of the letters, but I've sort of achieved what I originally set out to do.
Apotheosis! Good times!
