MO20 PLT HAD RWY INCURSION.

Narrative

AFTER LNDG AT MSN; BEING UNFAMILIAR WITH THE ARPT AND AT NIGHT; I ASKED FOR A PROGRESSIVE. THE SOLE CTLR ON DUTY WAS WORKING BOTH TWR AND GND. HE WAS BUSY; HARASSED; IMPATIENT AND ANGRY. HE DIRECTED ME TO TAXI DOWN RWY 13 (I HAD LANDED ON RWY 36) WHICH WAS LIT AND ACTIVE AND EXIT AT TXWY B2. WHEN I DID THIS; AND MADE SEVERAL CALLS FOR FURTHER INSTRUCTION; HE ANGRILY YELLED TO TAXI STRAIGHT AHEAD 'TO' THE RAMP AND QUESTIONED MY INTELLIGENCE IF NOT MY ANCESTRY. 'FOLLOW THE RAMP SIGN.' THIS I DID UNTIL I REACHED A DEAD END ALLOWING A TURN EITHER R OR L. I WENT TO THE L (N) BECAUSE THE ARPT BEACON WAS THERE AND I COULD SEE PARKED PLANES. TAXIING TO THE BEACON; I CROSSED AN UNLIT AND UNMARKED RWY. I WAS NEVER AWARE OF IT IN THE DARK. THE FBO AT THE BEACON WAS CLOSED AND WHEN I CALLED GND TO ASK FOR INSTRUCTIONS; THE SAME CTLR ANGRILY ASKED ME HOW I GOT THERE. WHEN I REPLIED THAT I WAS FOLLOWING HIS INSTRUCTIONS; HE TOLD ME THAT I HAD TAXIED ACROSS A RWY (HE HAD NOT SEEN ME DO IT) AND 'IF IT HAD BEEN ACTIVE' I COULD HAVE CAUSED AN ACCIDENT; THAT I WAS A DISASTER; ETC; ETC; AND HE NEVER WANTED TO HEAR FROM ME AGAIN. HE THEN DIRECTED ME TO TAXI TO THE S RAMP BUT DID NOT GIVE ME DIRECTIONS EXCEPT A SHOUTED 'GO BACK THE WAY YOU CAME.' IN SO DOING; I CROSSED BACK ACROSS THE SAME RWY WHICH I NEVER SAW AGAIN IN THE DARK.
