I rode across Kansas with Bikecentennial in '76 and remember the nice people and nasty wind. Others coming toward us had obvious wear on one side of their tires from leaning into the wind from the south. Eastern Kansas was my favorite, between Lawrence and Pittsberg (sp?).
Missouri was hot. Damn hot! Town bar to air conditioned town bar. Did 110 miles in 110 degrees, tires on my fully loaded bike leaving deep tracks in the pavement, going from Missouri to Carbondale, Illinois. College party town attended by many friends at the time, eagerly anticipated in the middle of my trip. Another story.8^)
Bikecentennial became Adventure Cycling. They have great maps. I still have all mine from the summer of '76. They publish a magazine too. I grace the cover of their 20th anniversary issue, I forget the month in '96. The incident of their taking my picture is another great story I have from the trip. Go!!!
