I'd go, but I am not paying $50 for doing my public service.
I don't see a charity making any money and it is likely a group or a guy making the money off of it. but it does not state it that I can see, so I be it is a money making enterprise for one guy.
If it was HOW or make a wish or some other charity benefiting I might consider it. I have seen many of these "tournaments" run for the groups, or one persons, own good.
I'd be glad to meet up and snakehead fish with any of you all any time though.
