The main A68 road south from the Borders to England goes over Soutra - a pass through the hills. Maybe there is a link to this.
This was an important road south in the middle ages, and Soutra was the site of a hospital run by monks which was investigated recently. They found evidence of advanced knowledge of herbs and drugs - watercress used to treat scurvy for instance. news.bbc.co.uk/1/hi/health/3745498.stm
I remember the trains on the Waverley line often struggling up Soutra Hill en route for Edinburgh Waverley , and if there was snow, guess where was always blocked? Yes , rosequartz, the "Souters" of Selkirk were traditionally shoemakers. Rumour hath it that Bonnie Prince Charlie knitted his army out with "shoon" (shoes) in Selkirk in his way south in the '45, undertaking to pay on his glorious return. They're still waiting.
