3) NATIONAL PARKS

While camping in Yosemite last year, the guy who admitted me to the camp ground told me that he was retired, and he spent every summer working as a temp in national parks! He didn't make a lot of money, but he got to spend a LOT of time in some of the most beautiful places in the country... and got room and board. How much would a 3 month vacation like that cost if you had to pay for it?

No idea how this works, but I will definitely be looking into this. If you have insider info, please post it here.
