Pollok Pathway .....

..... down by the riverside.

Plenty of people enjoying a lovely morning walk through the park.
I should edit that sentence because some folk were cycling, some jogging and having to share the path with the buggy pushers, dog walkers, phone users, strollers and the animated chatterers. 

There isn't a real arch formed by the tree branches but if you stand in the right place it looks like a bit like a tunnel.
