As you brought it up it reminded me to ask about Old Bewick, I was there a little while ago and never managed got to the stones.
It looks easy enough on the map, park at the houses, nip up the path and then take the path round the north or south of the hill then a quick trek uphill to the stones. First problem was parking - there were 'no parking' signs up at the houses and I couldn't find anywhere else to park so ended up down a lane next to the church. I then had to hike back up to the houses and up the track to the gate onto the access land around the hill. The bottom of the hill seemed to have a wire fence round it so I had a wander round the southern path until I got to another gate in the wall on the eastern side of the hill that leads into a small wood. I never noticed any obvious paths leading up the hill and as I was pushed for time and daylight I had to call it day.
So, first question - where is the best place to park and secondly should I have taken the path round the northern side of the hill (your fieldnotes mention going up behind the trees but I wasn't sure which ones).
Ta!
