Hi there all you helpful people.
On our way south we would like to
take time to go to Birdoswald Fort and
back to Carlisle. Since I don't know the
condition of the road, how long would
the 10 mile drive take.
I ask because we also want to visit
Keswick which is also off the M6
and I want to make sure we have time
to do both pitstops on the same day.
