I did two seasons ago. I actually had a tag for 47 and one for 41. Mainly hunted 47. I only touched a couple of the WIAs on the far north end of the unit. In both units there were 99 mulies to every white. It was tough as the whites only reside in the river bottoms that are all private, so you basically just have to hunt all the WIAs for any real chance at a white. And you really need a treestand for it.
I wont be doing it again unless i have a mule tag
