Rob - running them over occurs more regularly than you might think - Marsden Moor is open grazing land, i generally have to avoid sheep in the road on a daily basis, probaly easier to 'bag' one in the morning when they (and i) are less awake!!
keep us posted on the bake off. more than happy to bring the box along, its had about 100 hours running in now, subjectively it sounds better but hey, it could be that my ears are breaking in............!
