Has anybody been to the Lord Mayors fireworks recently? I went a few years ago, but can't remember what it was like? Does anybody know how crowded it gets? I was thing of taking my four year old, and standing somewhere near Waterloo or towards London Bridge, as that's closes to our route home. Would it be too busy for a four year old you think? He likes fireworks, so I'm not worried about him being freaked out by the noise, just worried we'll get stuck in town if it's really busy. Any recommendations on where it might be best to stand?
