4 am rule; the boat races were the stuff of legend, and eventually, someone was going to get themselves dead. I did it one time at Bayou Meto, and while I can say I saw it for myself and am glad, I don't need to do that ever again. There were some injuries here and there, and several years ago two boats collided head on, broad daylight, when someone cut the inside of a blind curve at the Hurricane Lake WMA. That WMA does not have a hp restriction, and they run 40hp and larger motors routinely.
The Game & Fish Commission cracked down on it pretty hard. They installed gates in the boat road just out from the launch; only one boat at a time can get through, and they mandated a minimum 100 foot distance between boats. They are also known to have wardens in boats out in the boat roads handing out tickets for various and sundry, particularly passing a stopped boat (theirs) at speed, rather than at idle as the law requires.
Like a lot of things, rules beget rules, and people look for ways to get around them. The 4 am entry was put in place because people would pay young guys to go sleep out in the holes and "save" them until the group showed up. Happened more when guides were allowed on the WMA's, but even after they were banned, there was still guiding going on. Game & Fish wanted the birds to have some time to get into the timber and rest, so they mandated that everyone had to be out by noon, and not enter before 4 am. That started the boat races.
The whole thing about getting there "fustest with the mostest" is another one of those things that depends totally on everyone else. Let's say I get to a prime hole - one of the "known" spots on Cache, Rainey, or Bayou Meto, at 4:40 and pitch my decoys out, set the jerk string, hang the guns on the tree, and wade the boat back into the trees. I am now at the mercy of everyone else's good nature for the next two hours, because Arkansas does not have a minimum distance or first come, first served rule on public ground. So some yutz can come motoring on in at 5 minutes before shooting light and set up 50 yards away, or immediately downwind, or both. A lot of groups will find a hole then send people out for a hundred yards or so with lights in as many directions as they can, to discourage anyone setting up too close. Most normal people don't even come close, but there's always someone..."you can't keep me from hunting here"
When there is water and people are moderately behaving themselves, it's not as big of an issue. Get low water years and everyone wanting the same few holes, and it can get a little tense.
Personally, I wish they would make a few more parts of the WMA's walk-in or non-motorized boats only. There are some sections of Bayou Meto that that would be dangerous because you have to pass by the water control structures, and on high water, the current would be more than any paddle/row could handle, but I think the results would be interesting to see.
