I've been having a bit of fun remapping unclean areas based on cleanmap and
remapping after the bot.  It's a bit like the initial TIGER cleanup, but
this time I feel extra pride at achieving even higher quality than in that
effort years ago.  (More experience, better tools, more familiarity with
tools, better imagery, etc)  I'll admit Columbus isn't as hard-hit as Los
Angeles, but having the right attutude might help cleaning up SoCal seem
less painful.  And if you could use another armchair mapper in the effort,
I'll try to bring my optimism with me.
