Love the vids Ritchie, even the upside down bits, you just have to pretend you are the pillion and not the rider.
I drove the pass long ago in the car with a manic, speed-freak girlfriend and we got tangled up with a bunch of bikes who were trying, but not hard enough...
When we pulled over in a lay-by for a brew, some of the bikes pulled in and one of the guys came over and said 'You should ride a bike mate.' Well, I only had two at the time but I took it as a high compliment.
Honister used to be used as a selective (timed and competitive) section on road rallies back in the day and it was as scary as 5#/+€ in the dark, especially for the poor navigators!
