Hey Karl - I remember using a spark plug - hollowed and adapted to a hose to air up. It took the place of the bike pump. We could actually air up all four in about a hour from scratch. Scratch was 9 or 10 pounds, and we worried about spinning the tire and screwing up the tube. Always carried a spare tube along.
I often wonder why some guys didn't blow up with the gas in the tubes.
Will I see you on Saturday?
