Agreed, 5am runs are best for me. like kris says, peaceful, cool....    Check out the posts under Equipment/Gear (or something like that), plenty of good info on reflective stuff. In addition to some built-in reflective strips on shoes, shorts and/or shirts i also wear a wristband or two. Nathans, the auto-snap-roll type. Works great, but it proved to be too stiff and tight on the ankles and would cut into me. I now wear on wrist(s), where i can constantly adjust it. The roll snap feature makes it easy, but it is somewhat of a hassle. I imagine the 'more cloth' ones lead to less irritation and hassle. And also best if you run against traffic, as a lot of people that early are drowsy and/or not expecting runners since you say your streets are "mostly dead".  cheers

I have a reflective vest I wear if I'm concerned about traffic in the dark.  Its super light and I forget its on, cost about $30 from an online running store.  I also use a headlamp sometimes if its very dark.  There are a few that are small enough that you can tuck it in to a pocket once its gets light out and you don't need it anymore.
