I'm not new - I've been jumped all over in the past for naming a river that was magical apparently.
Again, London is not a prime fishing spot - and I realize the hypocrasy of stating a river name because it doesn't contain trout/salmon, but unfortunatly that seems to be the harsh reality.
If someone complains we're 'ruining' the London fishing holes I would:
a) Call you a moron
b ) Edit the post to remove the offending location (I'd probably be a smart ass about it too)
London considers itself the 'forest city' - albeit its not so true.
