They don't , neither Newt nor Phone ,to the best of my knowledge, have fished the Swale, both live in the USA (clue's in the address under their avatar's) , they're both just being polite
I fish mainly on the Tees but have fished Bradford no.1 waters as a guest and they're cracking waters and they have a lot of quality river and still water to go at, if I was looking to fish the Swale more, then I would join no.1 as it represents really good fishing, Middlesbrough also have some very good waters on the Swale too but I guess it all depends where you live, how far you want to travel to fish and accessability to bankside, how mobile you are and how far you're prepared to walk along the bankside
Might help a bit too if you edited your details and said where you live
Don't expect anyone to name venues on open forums as it leads to poaching problems, trespass issues, problems for the clubs who own or lease the fishing rights and more importantly some clubs have a disciplinary procedure for members who publicly name venues
All I'll say publicly is that near to the village of Topcliffe you'll get as much quality fishing as you can handle by being a no.1 member
