Especially on the West Coast where you can quickly go from sea level to very high elevations in the matter of a few hours. I reported this quite a few years ago in the newsletter in a note from a California reader who had his sponson seams pop. He had left his sea level home in the cool morning and driven into higher elevations. Between the elevation gain and the heated up air, the air in the sponsons, which had been fully inflated when he left home, expanded excessively and popped the seams in places. Conceivably the same could happen if you start off on a shady cool morning with fully inflated sponsons and then drive, even at level altitudes, into a day in which the sun beats down strongly and the air heats up 25-30 degrees or more, not an untypical day in many places in the late spring and early summer. ralph -- ----------------------------------------------------------------------- Ralph Diaz . . .
