Forgot to mention: The JFK conspiracy Tour was very interesting - seeing all of the places, from the book depository (which is now a JFK Museum) to Dealy Plaza (which looks just the same, and is much smaller than I expected it would be) to Parkland Hospital to Oswalds rooming house to the Texas theater and many points in between. Had a presentation with slides, and then added commentary on the tour, and I'm convinced of two things:
1) Oswald did not act alone.
2) We will never know what really happened.
The analogy used by our guide was "it's a 500 piece jigsaw puzzle but there are a million pieces in the box" There are just too many pieces of data, and you can make almost any story make sense by picking and choosing what you're looking at. But the only thing that really DOESN'T make sense is the idea of Oswald as a lone gunman.
The guide also used the phrase "I'm as nervous as a long tailed cat in a room full of rocking chairs". That alone was worth the price of admission.
