If your stuck with those dates, then you have to hunt the lowcountry. Their gun season opens August 15th, where ours in the upstate does not open until Oct. 11th (Sept. 15th for archery).
X4 or 5...or however many, on staying away from Bostic. That place has taken a nose dive since I hunted there 10 years ago. Nothing but bad reviews now.
I have hog hunted with Cypress Creek. I would give them an 'A' rating.
Good luck
