Hoping to head off tomorrow and last night fitted the straps and positioned new roof bag under and made a note to not drive off with it on. In a rush today I managed to drive up the road to get petrol and lost it. I filled up and drove back which is about half a mile and it's gone. Some @&)) has nicked it already. Can't believe it, I feel such a plonker. It was a nice bit of kit as well.
