It's probably not about them just deciding to blend ethanol in all their gas. It most likely has to do with RIN credits, and if so there's not much the public can do about it.
Glad to hear you've decided to start hunting. I've been hunting and fishing for about 17 of my 25 years, but it has all been on leased land. Thanks for the info; I'll have to go scout it out soon. Correct me if I'm wrong but all you need to hunt a WMA is the "WMA tag" (for lack of a better term)...
