Antonine Wall

Day 9 of John Muir Way -24km from Bonnybridge to Milton of Campsie
This was an interesting section and not as flat as it has been so far - we followed some of the Antonine wall, taking in Croy Hill Fort and Bar Hill Fort. I realise how little I know about this... 
Sadly the weather was pretty poor - there would have been some good views otherwise... I wasn't sure whether I was going to make it but it did me good to be out.
