Heron on the dock of the bay

Lovely sunset again here on South Padre Island. If you look closely you can see a heron on the fence. I tried to get a closer shot. Unfortunately a couple drove up and the girl (rudely, I thought!) ran in front of me, quickly snapped a photo of the heron before startling it and it flew away! I don't know what photography etiquette is but I most definitely don't think she follows it! What's more, they were Brits! Flipping tourists
