Dan here you go...
Some really fantastic photos of your Sherpa "out in the wild", jags, and most welcome indeed, especially the sign commemorating the Battle of the Boyne -- Wow! Lovely bike, beautifully setup and detailed to within an inch of its life, all to the good. What a terrific mount for your GPS...fits right there as the stem cap. A fine job by your son-in-law, and blends in nicely with the rest of the kit. You can both be proud.
I've PM'd you with a fuller response. A real treat to see.
To the rest of the Forum...the photos you take and post literally open a window on the world for those of us overseas from you, and it really is a treat to see little snippets of your wonderful bikes enjoying their native habitats and, of course, you as well! Though I work everyday with this very technology, I am still grateful to feel a childlike sense of wonder at the things it makes possible. Our vast world can shrink to a neighborhood via this medium, as we sit around the virtual table and share photos, good chat, and mutual interests. It is so common as to be unnoticeable these days, but it is still nice to take a moment once in awhile to really appreciate the positive side of technology.
All the best,
