Rattlesnake Block-er

This brick is the only thing between a rattler (or any snake for that matter) and my front door.

This is a gate leading to a little alcove in front of my door. It has grating all the way to the ground except for this little corner. Even with the brick, there is a slight opening which I fear is still large enough for something through which to slither.

I'm going to have to find something to pile on top of it that will fit under the edge of the house. In the meantime, since the snakes have begun to stir once again for the season, this will have to do.
