Flat & in denial...

Two days ago, bike was parked in the living room, as usual.  But, I noticed something different... off... wrong!  I went over to inspect.  Flat tire.  The back one.  In all honesty, I have been very busy the past two days.  I really have.  But, I'm also a bit in denial and scared to mess with it.  Since I *need* to ride and I also *need* to learn how to fix my own flats, I guess the time is coming to deal with it.  Soon, very soon.  Profanity filled updates will probably follow...
