Ave, Herr Gilleland!

This sounds like a most worthy pursuit. And in the service of nature, no less.

Dr. Gilleland files this post under the subject heading of "typographical and other errors," but try as I might, I can't figure out which part, if any, is erroneous. What am I missing? At a guess, it's something forehead-slappingly obvious.

...Okay, so I looked up Wiltshire and Dorset. They're both counties in southwest England that border each other. The article that Dr. Gilleland quotes says this about the gentleman, Martin Hügi, who's doing a walk to see Britain's "greatest" trees (oldest? tallest? grandest?):

When I catch up with Hügi a couple of weeks later, he is in Wiltshire (478 trees and 402 miles in), enjoying the hospitality of Wyndham's Oak, the oldest tree in Dorset.

So now, the humorous "bilocation" reference in the title of Dr. Gilleland's post makes sense: if this tree is in Dorset County, and Hügi is in Wiltshire County, he can conceivably be next to Dorset County, but not in it. Unless Hügi possesses the saintly power of bilocation.

And before you tut-tut me, I know bilocation, as a power, isn't only attributed to saints.

And to confirm: yes, the tree is in Dorset.

My apologies to Dr. Gilleland for ruining a perfectly good joke by explaining it.

ADDENDUM: if "a couple of weeks" means literally two weeks, then covering 402 miles in two weeks requires one to walk incredibly fast. That's almost 29 miles a day, or 46 km/day. Yikes. It's possible to walk at that pace, but you've got to be incredibly fit and/or incredibly determined. If "couple" more loosely means something like three weeks, then that's almost 19.2 miles per day or 31 km/day, which is doable even by me. Hügi, who works for a tree-conservation and forest-restoration firm, looks to be young-ish and athletic, so maybe he really is going almost 30 miles (ten leagues) per day. 

His Twitter account is here; he gets several hundred views per tweet. I see he complains a lot about foot soreness, which isn't surprising. I had to scroll down quite a bit before I saw some numbers: 422 miles in five weeks. Okay, so that's a bit slower than my pace across Korea. He's averaging about 12 miles (19 km) per day, but he says he's sometimes walking up to 10 miles even on supposed "rest" days. He's given himself something like four or five months to do the entire 2000-ish-mile walk down from Scotland to England. I hope he finishes without getting in trouble at his job (he had to take a leave of absence), and I wish him good luck. The idea behind his trip is awesome, and I salute his effort. (I also couldn't help noticing that his tweets bear all the marks of the typical Brit's hatred of commas.)
