OK, an update: A great first bivvy, helped by a roaring fire, Tallywhacker, Jaegerbombs, sloe gin and Jack Daniels 8O
All went well, our fairly basic kit did us proud and we were warm and comfortable. Riding home soon after first light with mist hanging over the fields was great.
Now to plan the next one, perhaps a bit further afield and on a night when I don’t have to work the next day…
