crumbs... I still have so much to learn. Well, thanks all, got enough here to keep me busy for a week I reckon. I did not realise we could go off and do our own thing, thought we had to traipse dutifully back to base as soon as the patrol was completed. What can I do about refuelling though? Getting a bit low to do too much gallivanting up and down the coast... time I went back and looked at the guides I think.
