Hi all
I'm returning to the UK on the 20th of July for around three weeks and was wondering if anyone knows of any locations for bottomless river mud or Bogs any Essex or Suffolk area?
I've been to many of the quarries but wanting to try something different if anyone knows of locations and is happy to either show me or I can accompany

What about estuary mud?

As good as it looks, I've never really found it my sort of thing.
On a couple of occasions I have tried it. I found it either not very deep and stink and on both occasions cut my feet on shelves and other debris laying at the bottom of it so now tend to avoid it for that reason
