I did run aground on Breydon, not on purpose, but because i got myself muddled up with the marker posts turning from the Berney Arms towards Burgh Castle. I was lucky and was only just beyond the marker, so i easily extracted myself when the tide rose.
Whilst i was extremely annoyed with myself at first, as i have made that turn multiple times and never had a problem, i calmed down and spent a very pleasant day sat on the mud watching the birds and drinking a few G&T's to make me forget how stupid i had been in the first place. It was certainly very peaceful.
So whilst not an intended experience it was a very pleasant one.
