With the way Ed was burning calories doing that hike, even if he had caught a rabbit, or a fish, he'd need probably four of each a day PLUS the plants to compensate. An average rabbit's good for like 600 calories.
ONE MRE = 5,000+! CALORIE / ENERGY MANAGMENT! KEEP YOUR FEET DRY! If your crippled with infected soar's, your just worm food waiting to happen... "Worms gotta eat to"

And those are 3/32" snares for stuff like coyote, fox, badgers. You want 1/32" snares for rabbits. You cant keep snares in a mesh bag with your gear, picking up all kinds of YOUR scent. Should have packed them in a air-tight baggy with some rubber gloves.

I'd love to do his trip! Probably like someone else there for company. And STILL not make it 90 days!

Ed made mistakes, but it
HAD to be real!
