So I think I may be taking the kids to a different lake after seeing this.  I saw this on ER once, never thought it actually happens. 
Check out the link for the full article.  Doesnt' say that it is for sure that the boy got the parasite from Elsinore but it never says that he didn't get if from there either. 
Just thought you should know.....

Heard about that on the news the other night.

You know those big things floating on the water - the ones that aren't the outhouses? Those have HUGE props below to try and stir the water so it doesn't become stagnant.

Last time I was there, there were a few huge fish dead and floating for no apparent reasn. The news article came out about 2 weeks later and I decided for me I'm done there. 

When I first heard this story, I admit, I was a little worried about it.  But once I finally got on the internet and google'd it, it is actually more common than one would think.  It doesn't happen all the time but it did happen twice in Havasu last year and nobody made a big deal about that.
So yeah, it does suck and it's pretty crazy.  But I guess stranger things have happened.
