I have never been convinced there are in fact purps there..I think the "bog type" is wrong..no floating spagnum mats...but if they are there, I doubt you will be able to easily find them, it is not a "hike friendly" swamp!
I have tried it..not only did I not find any CP's, I didnt find any promising CP habitats..
but its also a BIG swamp! perhaps I was just looking in the wrong place..I cant say for certain there are *not* purps there..but IMO its not promising..
Have you been to the swamp with the boardwalk? near Houghton?
