Spring Cleaning

As I just posted elsewhere, I finally got around to doing some of the winter maintenance on my bike.  I replaced the air filter and oiled the chain.  I intended to change the oil and oil filter, but ran into a small snag...:

WHERE'S MY OIL FILTER?!?!?!

I think I really need to wash my bike!  That's on my agenda for tomorrow, followed by an oil change.
