Buy a horse. lol

I'm kidding. But there's lots to be said about carts or beasts of burden. Of course, lots to be said about getting blisters since you're probably not used to moving a cart for extended distances.

Do you plan strictly on walking? Where do you plan on going that you need so much to get there?

Bicycle bags are an option as has been mentioned in the past, if you decide to bike out. There are some front/back bag combos that help distribute the weight a bit. Personally, I found in high school that I could carry a 50lbs bag for days on end. I didn't like it...

Somewhere I read that a backpack shouldn't be more than 1/3 your weight. Most folks can go up to half their weight for a limited time period. If you're not in good shape though, you're just asking for an injury.
