OK, I'll show you mine....

I've owned my Westy for 8 years and never thought much
about the gooey blob that gets soft and sticky after
cooking.  I guess I know now where it came from.  I
have only two bumpers above the drain tray.  I'm sure
there is a story behind how it came to be where it is,
but I'll never know it.

BTW--mine are gray (or grey) as is everything in my '87.
