@fellsnude and @jon-tanner 

I'm sure you are both right. However, my OH would certainly not condone my nudity seeing that these 'officials' were present and could potentially use their equipment to see me. To keep her happy, I refrained from stripping off when otherwise I may well have done so for a while.  Pity I can't return to Ross Sands in the good weather we're currently having because anyone able to get there will be in a for a treat.

I hope to be back there next week!!
