I'm leaving on a trip from Wisconsin to San Fransisco and up the coast to northern Oregon and then heading back east back to Wisconsin. I am leaving exactly a week before you are April 11th. I am heading through Kansas and then Colorado (hopefully) to get over to California.
I don't know what route you are planning on taking to Seatle, but maybe we could ride together for a few days to California or further. Kansas or Oklahoma would be a good place to meet with you coming from Miami and myself coming from Milwaukee.
