I've been out of the loop for a while, but I feel I should take responsibility for this hahaha!
Well, it was me who added it (and a couple of other Perthshire Pairs!), but I certainly didn't come up with the in-joke of naming them two-posters. I actually can't recall where I read the first description of Perthshire Pairs (I like that :)) as Two-Posters.
Tiompan- thanks for all the recent discovery/posts on here. I visit Loch Tay area regularly (but not regularly enough!) and will add your latest posts to my sites-I-must-see list. Yeah, the Tullich Hill CM's- it's hard to tell from the pics, but are those deliberately carved run-off grooves from the CM's on the edge of the stone?? Hmmm- v interesting.
Cheers guys,
Martin
