Looks thick, can you get "under it" by low crawling or you gotta just push your way through it?
in most areas there is no getting under, if you are where it is about 10' tall, the undergrowth may not be quite as bad, but usually just have to try to push your way through, moving it side to side where is isn't as thick of branches....
only savior in some areas is that the animals will make trails through it, in the case of hogs if you want to crawl through their trail, have at it, thats where they may be coming when they make a break for it....just hope you aren't on the same one lol.
I know there is similar vegetation in FL and TX, not salt cedars, but thick stuff, can't win, of course the hogs are going to go for it when they need to get away or to fight
