I'd like to do more of that myself... Beware of rattlers in the summer. Seriously. When you get off the trail, especially near rivers (i.e. w/n 50 yards of the bank), you better expect to see them. I've never had one be aggressive towards me at all, but I see a lot of snakes in the park. I think you should be able to get about anywhere you want w/o having to do any chopping and hacking at the brush. What always amazes me is the ease with which wild animals move through brush that is basically a total blockade to humans.
I got no style, I'm strictly roots.
