I'm glad the blog posts were helpful. I always carry an Abus Bordo when I travel, because I just don't know what kind of neighborhood I am traveling through. Regarding the comments about the trails in Pittsburgh at night, I rode them at 2am from the Amtrak station to McKeesport to get my car. I had a very pleasant ride with no incidents and the only people I saw on the streets at any location were police officers. I can' t say it's always that way, but that was my experience.
