Time of year
The first picture isn't Nelson Drive, i don't know where you people got this photograph, but it's definitely not Nelson Drive or anywhere near the area. I know because i've lived there since the early 80s. Get your facts right before you publish copy onto your site.
Dirty looking graffiti, perpetuating the myth that the loyalist people of Ulster are somehow "special" in the eyes of the royal family of England. Serves no purpose other than to mark someone's "turf" and should be removed as it has no place in a modern society!
This was not much of a tour, just a walk through Sperrin Park to Broomhill Avenue via Nelson Drive. All the murals I saw were on Sperrin Park. Could not find any on Nelson Drive. Otherwise a good peaceful walk. Enjoy
