Here's a video of a blogger getting a personal tour of all the areas in question from Frank Taaffe. I didn't care for all the dialogue, but it gives a good video portrayal of the routes, neighborhood and for the first time I've seen, the inside of the clubhouse and position of the cameras.
Taaffe asks some good questions about why Trayvon chose to walk the longest way around if he was going to his dad's house.
