Totally random thought, but why the sam splint? You break a leg and you're not going anywhere. You break your arm, and you're better off going to the hospital (where it's fairly safe).
You plan on splinting yourself? You ever seen/done a splint before? Kinda painful.
OK, I'll let the debates continue on the original topic.
I was actually planning on helping others with it. I'm certified in Wilderness First Aid (though this is an urban setting). It doesn't take up much space since I have it folded flat. Maybe it's the Scouter in me.
I agree with Tom_L regarding a quiet E&E, if possible. That is my preference. My plan is to follow the railroad tracks out, since the roads will be lousy and these are a more direct route. Unfortunately, they go through some rough neighborhoods in spots. Be prepared.
