Scientists ? a vet ? electronics ? Give me a couple good ol country boys and their wives" IF" I had to be in a group and we will stay right here in the woods of east TN and survive well !
I am beginning to wonder if you ever bother to read what people post. You are very quick to condemn. The group I have in mind has 4 "good ol country boys" and their wives - well, 2 of the boys are better described as "good young country boys". As soon as you, or anybody else, take a shot or light a fire you give away your location - and you will be up against other "good ol country boys" in any confrontation. You will also be up against ex-military city boys who have been under fire before too. If you are not in a group then your attackers have the very easy task of just wearing you down by sleep deprivation.
Your 15 miles out in the woods is a morning's stroll for 4 of the people in my group. They often cover 50 miles in a day just for the heck of it, climbing what are known as Munros on the way, in Scotland, in winter. That is just one of the reasons they are in the group. You started the post asking for peoples' opinions, but you continually attack anyone who thinks differently to yourself. Most of the other posters on here are at least trying to reason with each other, even if they have differences of opinion.
See if you can read and understand Robert Burns' "Address to the unco guid".
And just to show no favouritism, I disagree with Rob-D about a vegetarian diet. As now, I would, if possible, consume a large quantity of fruit and vegetables, but also eat meat and dairy products. He does say to eat fish, and I have that at least twice a week. I do not count calories, but consume a lot and have been in the weight range of 198-202 pounds for over 40 years. I do physical work about 8 or 9 hours a day 7 days a week, but I know fine that I am no match for somebody 40 years younger, or with a gun big enough to blow holes through my walls. And neither is any other old man.
