The track led on to reach Old Dunsmore Farm and the few other buildings in its vicinity. At the end of the track I went straight on along a footpath, initially between a hedge and a fence. Over a stile I continued rising half-left up a grassy hillside - there were some cattle over to my right. Across another stile near the top of the slope (where there was a nice view looking back) I continued through a meadow of long grass to reach the lane through Dunsmore, where I turned right to reach the duck pond and chapel in the centre of the hamlet.
Near Dunsmore Old Farm - I continued straight on along a path going half-left across the hillside (again my camera is lying, it is steeper than it looks in the photo)

I stopped to look at the map and consider my options - it happened to be sunny at this point, so I didn't think to take the possibility of rain into consideration even though the ominous grey clouds were still around. I decided that I would carry on and include Bacombe Hill in the walk (even though I could already tell I wouldn't be feeling great the next day), and furthermore I decided to try a new route to get there. So I continued on along the lane which soon left Dunsmore and headed downhill - almost immediately the sun disappeared and again it looked like there might be a downpour. After several hundred yards I turned left at a footpath sign, the path following a drive between hedgerows. I stayed with the track when it turned left (actually I first tried the path going straight on, but soon had to turn back because that right of way was blocked by a field of maize with no way through) then when the track went right I made my way into the field on the left by a white post with a footpath waymark (there were brambles and nettles here, it wasn't easy). The footpath now followed the hedge on the right, which turned left and then right (with the garden of a large house now on the other side of the hedge) to reach a small wood (which isn't named on either Google or OS maps). I went straight on through the wood to a path T-junction, where I turned right (I was now back on a path I'd walked before).

I followed this path through the unnamed wood, and then on alongside the edge of a maize field (this was the field that had forced me to turn back before - annoyingly the maize here was much shorter than in the far corner where the other path entered the field, so perhaps I could have ploughed my way through after all). There was a nice view ahead of me over a broad valley (soon to be spoiled by HS2 - grrr! Stop HS2) towards a wood-topped side valley called The Hale, near Wendover. The skies were very dark now and I thought I might well be in for a soaking. I then turned left (I didn't see any evidence of the other path emerging from the maize field at this point) following a hedge on the right now past a smaller maize field.
