I intend on trying it myself. I am trying to patiently await the arrival of a pv 8yd kingussie in MacLeod of Harris as well as a sporran.
As for blue collar, I guess you could say the physical part is. I'm a professional urban trapper so there is alot of ladder works with squirrels and bats but I also do quite a bit of ground work with moles, fox/coyote and beaver. Of course I can not go regimental with the ladders plus need to be able to strip down to don chest waders.
My only real concern is attic and crawlspace inspections since it's hard enough on my arthritic knees in pants.
