I went through the Snake pass and a few roads on Saturday lunch time.....
WORD OF CAUTION!!!
1) There was a camera van there - stopped spoke to them, wasn't a busy day apparently LOL
2) Water in a few spots on the road that the sun doesn't get to - especially on corners - this might turn to black ice with these temps!!!
3) Very windy and loads of sheep on the road!!! Been going through that road for the past 4 years first time that I had to slow down just incase one of those decided to get upgraded to a yamaha sheep
have a good run and stay safe
