Dinner Island

I picked up the 2nd hunt in 4 weeks and was hoping someone could answer a few questions I've got. I've never been before but a couple guys have told me it's a good spot. I saw that you can ride 4 wheelers but wanted to know if they have to be registered to be on the wma? Can I use my 2 wheel drive pick up or is it too wet or too much sugar sand? I'd hate to get stuck trying to scout by myself during the week. Any other info would be great. Pm's are fine if anyone's interested. Thanks in advance guys. :toast
