Now, my earlier prayer was answered in it's entirety. Just as I was entering Sibley, the sky opened up and the rain began to pour down. I dashed under a gas station roof and put on my rain jacket and zip-locs. I'd asked for it, but it was alright. I was right.
Rain is no problem.
If it takes rain to stop a headwind, bring it on. As the truck driver in Alton had said, the spray from passing trucks was not desirous. I learned to wear my sunglasses on my forehead so that I could quickly drop them down over my eyes when a truck passed. The rain only lasted a few miles and the winds died down, too. As I crossed the border into Minnesota I removed my rain jacket and shoe bags, which by the way, were holding out fine.
