Well it may be a little more crowded during moder gun season (but not as crowded as, say, Wedington WMA), but because it is so damn big (280k acres) all you have to do is get off the road a ways and you won't see another hunter. Overall, White Rock is a petty good WMA for sure. I'm not sure how much more I can tell you than what I wrote in the article, but I'll sure give it a try.
Access from the north can be obtained off State Hwy. 16 by way of several county and Forest Service Roads located at Dutton, Delaney, Combs, St. Paul and Pettigrew. h. You can find a link to the White Rock WMA map here:
http://www.arkansasoutdoorsonline.com/arkansas-wma-mapsThe bad news is, White Rock pretty damn rugged. The good news is, there area lot of access points and lots of old service roads throughout as well. But again, everybody else is going to be using these as well. It would help you out a lot to go scout it. Not that that is any breaking news to you. However if you spent a day hiking with your GPS and topo map you could get a good idea of the terrain, acorns, water sources, etc. The farther you hike on opening day, the higher chance of getting away from the crowds and finding a good buck. The topo map would help you find some travel ridges and heavily traveled draws, and may, most importantly, help you avoid the roughest terrain that is going to wear you out fast!
As far as deer go, people say the population is good, but it's not a banner place for giant bucks. Then again, just think about how much of it is never hunted because it's too hard to get to, and let your imagination run wild. You know there has to be good bucks in there. I know of some people that have killed some good ones in there too.
