I met this little boy and his mum in November as Autumn was moving to an close. The leaves has mostly fallen off the trees but the grass was covered in a coloured carpet of leaves. The little boy brought a few cars and spent some time playing with them in the leaves. At one point we had to stop taking photos to try to find one of the cars which he had buried in the leaves. Thankfully it was found.
Carlisle has some excellent places for family photos, all close to the city centre but quiet enough that you can have family photoshoots without having an audience. Spring, Summer, Autumn, Winter whatever the season there are places to have some fun.
