A little aside here while we await the gentleman: Stilly, I found that Devils Club is handy for making one's way through the boggy stuff. You need boots, of course, but if you step on the devils club near its base it lies fairly flat and will displace your weight in preparation for your next step. Much easier to navigate than the wimpy but rebellious alder hells we have here.

Of course, if the Club swings at you and connects---! I remember one time when I worked at the house museum a park ranger stopped by and asked if I could get some spines out of his head. The problem was that the ranger's hair, while short, is very blond so the almost-transparent spines didn't show.   I didn't really help him at all.
