I also just booked a flight to Scotland - my first trip there! I will be traveling by bike from Glasgow to Glasgow, planning on about 1000 km (travel camera: Rolleiflex 3,5F with mini-Berlebach wooden tripod). I will be there from July 8 - 22.
I'll have my fingers crossed for you guys nearer the time, but if you ever want to know what it is like in Inverness, there is a webcam at the link below. You can change the view to show more of the river and it's pretty high just now if you look at the North view!
