airing down is one of the tenements of offroading. street pressures just don't work as well offroad. so I give you our last day camping near the dunes, after I had already aired back up to street pressure for the drive home, and everyone said "let's go down to the lakefront to watch the sun set. I figured since I wasn't doing anything crazy, just driving over to the beach I could get away without airing down. nope. got as far as the main drag would take me and got stopped by the very first little hill. got out, aired down, and drove right out.
couple more from earlier that day
