If you get crushed limestone, water and pressure (roll it) will cause it
to compact into a solid mass.

Under NO circumstances should you spread pea gravel or sand in front of your
hangar door.

Our hangar neighbor did that last year, and that damned stuff ended up all

You can get the same result with a few bags of asphalt patch, which is more
durable and won't blow away.
