After ride 27 of my 30 my low tire pressure indicator went off. Stopped by house to grab a bite and then went down to car to drive to tire shop (figuring slow leak). Nope - totally flat. Pulled out sealant and air compressor - and the fluid started coming out of the sidewalls - so tire is shot, can't get somebody in till tomorrow (unless I convince complex it's an emergency - but will prob have to get it towed anyway) and I'm 3 away from the bonus. Today sux!
