As per usual, late ............ Great theme of arches and tunnels, Pat. I am battling again to comment though on the posts, I can see them but comment sections seems to be closed off???
My first is the entrance to the 1st of 2 Hendrik Verwoerd Tunnel just before Louis Trichard, in Limpopo on the way up to Beit Bridge, Zimbabwe
My second might be a bit far fetched, but I liked the arches the branches of this unknown bush or tree was making , it seemed like it was weaving a framework, to me. Taken at Thipise, Limpopo
My 3rd and last, yes no cheating or bonus shots for a change............ sorry, too tired to think....
Back home in Botanical Gardens walking on a trek up the Witwatersrand Berg, came though a small gate, to what must originally have been the homestead, through a tunnel of trees and bushes to the river on the other side.
Will be back later to try and see if I can comment properly on all the wonderful entries.
