Six degrees minus a few

I just got this email:
Rob,

I have a story for you. A lesbian couple I know have a son, Brett. I've known him since he was 3. I've been involved in his life for the last 15 years, active in his school and with his friends. He graduated on Wednesday the 9th. Today, the 12th, his moms had a party for him. I was originally not going to be able to attend, but my father passed away and I found myself in Seattle. I went to the party. Several of his friends that I'd known since they were small were there. One of Brett's friends was there with his dad, Mark. I've known Mark a long time from our working together with the boys at school camp etc. I started talking with Mark and his son, Brett's friend. Mark's son started telling me he had just biked across the US. I told him about you. He found that interesting. Brett's friend Joey knew you. You probably know him better as Joseph:

Republic, WA. It never rains here.
I met my first long distance biker, 19 yo Joseph from Seattle, who is biking home from Richmond, Virginia.
