I did too and thoroughly enjoyed it. Met a couple from Massachusetts who were also on the tour. The most pleasant surprise was they weren't liberals.
I really enjoyed mine. We ended up at the Twelve Bells pub (the pub where supposedly a victim had her last meal/drink), and had a great time.
I bought him a pint and tipped him twenty quid, plus bought his book. I really had a nice night. I’m glad you liked your tour too.
The best of the Ripper tours are run by Yeoman of the Guard (Beefeaters) from the Tower of London, as a way of generating extra private income. It can be hard to identify these tours though.
I’m surprised nobody’s claimed they have a “ripper” behind their zipper yet.... Oh wait. Can I say that?
