On the way home from my sister's - down the main drag through town I came across a cop car and a tow truck with lights flashing.  They were the only one's there besides the bike.  I assume the driver lost it on the street and skidded onto the sidewalk since the bike was laying on the sidewalk.  I think they said on the news that they are looking for witnesses.  Don't know whether another vehicle was involved or not - gonna have to watch the news late tonight.  Two riders died last week and now this - scary.
