The following are just a couple of my thoughts on the subject. An organization or organizer holding an event should look at some small, but in some minds significant things about locations of said events. I would think the average tournaments angler spends on average no less than two days pre-fishing for a tournament. Of course the amounts of cash for certain placing is generally the largest draw for these anglers. Then to arrive at the area to be the mainstay for camping and or tournament headquarters to find very little for amenities, such as washrooms, running water or power to name a couple of things.
Most people let alone anglers feel is necessity wherever they travel.
Organizations or organizers should put these small things first and foremost. If you make anglers comfortable they will attend. Good facilities are one of the best things to help draw to these events. Of course it is tough at best in some areas to have these so-called luxuries. But if promoters brought in toilets and power, even for a small charge to all would probably help.
