Thats the thing with most hunts in places like Texas. You may be hunting high fence but it could be on 5-20k acres and not always super easy. Still much different than a western hunt.
One trick I have used for food if using a Mountain House type meal is to only keep one in the packaging and all the rest in individual ziplock bags. Then just reuse the one original packaging to cook them in.
Not a ton of help but had a buddy hunt it last year and shot a 6 point bull. I think he hunted almost the whole season but stressed the importance of knowing how to call.
