Very optimistic to regard the Dhorlinn as sand: pretty much mud IIRC

From ESRI imagery - construction ongoing here, need survey to check street names; also across the railway line.

Is this street also known as Rousay Wynd?

IBM station has now been closed, but will most likely reopen when there is new development on the former IBM site.

Area is a Local Park

There is a hamlet at this location called "Meigle". The main part runs from the A78 junction to approx. the point I've indicated, and also on the other side-road a little to the north, from about 200m east of its A78 junction to near Skelmorlie Castle, and between the two roads . Several outlying farms and holiday chalets also use Meigle as their postal address. (Note: the same place-name "Meigle" also occurs in Perthshire).

Can someone please confirm whether "The Ritz Cafe Millport" is located over here?
Thank you.

Major issue! Coastline of island seems to be missing.
