Sorry for a late reply, and especially to Eugenitor... And, I've just lost an hour of tired structuring of my reply, because of logging in differently, and just for an hour. So, I'll be brief.
cganya, well, my advice about chapters applies mostly to print, I guess (because on the Internet nobody cares). If you work is pretty short, and is frequently chapterized, it's going to look amateur, so, it you ever decide to publish, keep that in mind.
Yeah, descriptions are a matter of taste. I, personally, enjoy works on both ends of the range - the Hobbit, and the Lord of the Rings; and works of Philip K. Dick, in whose stories the protagonist is basically never described, except through thoughts, if I may. But then, this mental description is quite extensive. So, it might be that description is required for fleshing out the story, but it can be of different kinds. Although, for your story I might have pushed it too far... because when you start finding flaws, you tend to find them everywhere.
Eugenitor, I've read it, and a good thing is that it's definitely not boring.
However, I've got a few criticisms to share.
If you choose to edit it, pay special attention to the dialogue at the beginning. Up until the first helicopter ride the boys end all their sentences with exclamation marks. Kind of funny.
You tend to switch viewpoints quite haphazardly sometimes. Like the helicopter ride, when we randomly get into the head of both boys, and then Blakesworth. It's pretty confusing, and you could easily handle the story with single carefully chosen protagonist.
Then, it might be debatable, but the scene where the Mom cleans up feels redundant. It's probably because not much happens in this scene, that is, no important information comes up, the Mom is not threatened in any way. It might be related to random view-point switching, because if we had a secure mental anchor, we might feel the scene to be justified just because the protagonist was there.
And finally, the very beginning - it might be tense, or viewpoint disconnect, but the social observation feels out of place and amateur. First, there is no character to tie it to, so, the author speaks up for the first and the last time in the narrative, or something.
Phew. Writing is rewriting.
