Had to tap out 40 miles from Yuma. I'm a little disappointed, but I had to listen to my body. It was screaming "you need AC, you need to relax, you need water." So, after deliberating for a half hour, I finally gave in. I'm pretty sure what got me so exhausted was those back roads. Not having the wind in my face for an hour, really put a hurtin on me. Currently: I'm in an AC cooled motel room in Wellton, AZ for the night. This is why I budgeted like crazy the last two years, and why I travel on a budget, so when unexpected things happen, I can get a motel for a night. Thanks for everyone's support! On to San Diego tomorrow.
