Soothing rumble of motorcycles

Ah, Rolling Thunder, how I have missed you. (clicky disabled) The soothing rumble of motorcycles under my feet.  My office is perched above the parking garage entrance/exit.  And may I just say that motorcycle riders tend to be the most well behaved guests.  They clean up after themselves.  The worst thing we have had was a domestic dispute last night.  Much better than National Police Week....
