| When I stopped by the airport this morning, dark clouds were moving in 
from the northwest.  A Falcon jet based locally contrasts with the clouds.

I noticed the Airport Manager busy on the ramp, but couldn't figure out 
what he was up to, so I walked out to ask.  After trying weed eaters for 
grass & weed control in cracks, he has found that a gas torch works 
better and is easier on the back. Here are two shots of his approach to 
weed control.

Apparently the fire gets the roots, for a longer lasting result. The tar 
cools back to its normal consistency. 
Comments and critiques welcomed and appreciated.
