Did it twice - once alone (Eugene - Los Angeles - Philadelphia), once as newlyweds (honeymoon by thumb, Madison - Berkeley and back). 1971 and 1974. Good idea to have the bus fare, just in case. How will you take care of water, food and camping gear for the burn? Seems like a disproportionate number of my longer rides were with newly divorced men who had to get some anger off their chests. If you're going straight through, five or six days should do it. Looks like you're planning to dawdle and look around. Good idea. A "home to BRC" sign would work best a week or so before the event when there are many burners on the road. Don't know how it will work in July. Have a good time.
