Ended up cycling across to St Andrews last Thursday for a chunk of the International Sax Congress, and then back as far as Linlithgow on the Friday. Blimey, the A91 is a dull, dull road. Hedges either side so there's no view, very few villages to break it up, and loads of lorries. Fife Coastal Route by contrast is pretty pleasant.
Thoroughly confused by the bridges though. Had to resort to a detailed look at OSM to dig out how to join the cyclepath for the Forth Road Bridge, and had similar issues with the Kincardine. I don't mind cycling on dual carriageways, but I'm not keen on joining them just as they stop being a motorway...
Still, didn't get rained on once. Result!
