I tried 18C yesterday for the first time and darn if I didn't want to remove some dead vegetation.
(cool hole though)
Did we put all those dead logs there or is it natural? It's kinda cool that you have an obstacle there, but I felt like all the real small twigs hanging off the large branches which you can see from a distance, should be removed. Also, it's just kind of a pain in the butt to walk through those dead logs as your last task for the course, in other areas of our course a buildup of dead branches means "do not enter", right? Should be thinned out a little there would be my .02
