I think the heaviest pack I hike with is about 60 lbs. And it always felt like I was practically floating when I took that off. I literally can't comprehend how horrible it'd feel to carry 100 extra pounds every minute of the day. Not to mention that the way these discussions usually go I'm sure that it's 100 lbs over an already overweight point. So probably closer to 150 extra pounds or more.  It's always astonishing that these people endure it just to have a 32nd serving of twinkies every day.  Edit: I just got back from the store. There's a twinkies cereal. Holy fuck, just.....WHAT. It has 16 grams of sugar in a single serving. For comparison, an adult man is supposed to max out at 37 grams per day and women at 25. Twinkies have always been my goto example for mindless gluttony. The fact that it's a cereal now is borderline incomprehensible. Well, I guess it's now easier to get up to said 32nd serving.
