Hey thanks martin, yes that was me, I rang RAF valley at about 3.15pm and the bloke in the ops room said "Oh yes we have an avoid all day on cadwest due to helicopter operations" but hey it beat work and it was good to meet you and the other stalwarts on the hill and thankyou for the advice on predictive focusing, hopefully i will get a chance to use it next time.
@Ziploc...sounds interesting I shall google for operations between the 5th and 16th...I am hopeing to be back before then too!
