it's such a little thing...

...but I'm glad it's fixed.  

There was a gap under the storm door, and Nathan's dad made a comment along the lines of, "One day you're going to open the door and a snake is going to be sitting there."  Yuck.  Needless to say, we haven't been keeping the front door open.  But a quick trip to Lowes for a $10 purchase and a little work done by Nathan has given us a sealed storm door:

I still don't keep the door open during the day, but we keep it open a lot on the weekends.  Sorry, snakes, you're not welcome here.
