I love Twittens, they are like Alice in wonderland portals!
Worthing has a huge amount of Twittens. It’s a local word to Sussex, you get them in Hastings, Chichester, Lewes and Brighton. I used to use one to get to work and only realised recently that you can trace all the way to Cissbury ring and probably well beyond, with the occasional gap from modern era developments. One upon a time these would have ben the main route of traffic to Worthing, the A24 of it’s day!
