Thanks for the link Luddite, but too late! Today about 180 miles from Badcall Bay to Ullapool on totally empty roads. Slightly busier into Inverness, then the usual shitfest at Inverness, even though it's BH Monday. Then more deserted roads to Grantown on Spey, Timontoul, and over the Grampian Ski Resort, finally to Aboyne. We now stay five days to do some hiking. Very pleased to have done most of the NC500. The only part left is the coastal route through Gairloch. Save that for next time.
