if you have more than one track session in a day, it makes sense to save the heat cycle and keep the tires warm. but, if you did got it to work, why the face? the building process, though, is only the beginning. don't sniff the glue... sniff and eat it! i am so grateful that you are going through these books and giving us your reactions. i think this semester has gotten off to a running start. the opposite of open debate is passive silence. we may never understand why this has happened, but someday we will fully know.
