Narrative:

Before engine start, we monitored ATIS and picked up clearance on 121.6. Clearance controller was very rushed and gave us preliminary taxi instructions. We advised engines were not started and could taxi in 1-2 mins. He said taxi to and hold short of D5 and monitor ground on 121.75. I did not understand the D5, as normal procedure is to go to end of GA ramp and hold short of D7. However, he was too busy to break in and verify, so we started engines and went to end of GA ramp and held, monitoring the ground frequency. His hurried instructions and inability for us to get in a word with all the frequency traffic put me in a rushed state of mind. Also, I didn't understand why not using ground metering. Ground controller contacted us and chastised us by saying 'I've been trying to get a hold of you....' we had just started engines and were on the ground frequency immediately after engine start (2 mins maximum since talking to clearance delivery). Ground controller then cleared 'to taxi to runway 22L behind the jet off to your right.' I looked to the right and for some reason I taxied to the right, this was my mistake. I knew runway 22L was pretty much straight ahead of my current position at D7 on GA ramp. I don't know why I taxied to the right. However, when on taxiway D (wbound) and looking forward, I saw other aircraft coming eastbound by D5 and holding for me (they knew I was wrong direction). Corrective action was me contacting ground and asking if he wanted me to 'duck into D5.' at this point, I still must have been thinking he was sending me to runway 22R. The ground controller said 'negative, do a 180 degree turn and taxi to runway 22L.' at this point, I realized my mistake, did the 180 degree turn and taxied to runway 22L (ahead of the aircraft I was supposed to follow). No incident, no close call. I taxied about 100 ft in wrong direction before correcting. No runway incursion, no other aircraft involved. Contributing to this, I feel, were 2 controllers too busy to 'deal' with a little guy, and my perception that at ord the GA guys are treated differently, even though in my few experiences there this is not the case.

Title: PIC OF A TURBOPROP SMT TAXIES THE WRONG WAY TO RWY 22L AT ORD AFTER HOLDING AT THE WRONG TXWY EXIT FROM THE GA RAMP.

Narrative: BEFORE ENG START, WE MONITORED ATIS AND PICKED UP CLRNC ON 121.6. CLRNC CTLR WAS VERY RUSHED AND GAVE US PRELIMINARY TAXI INSTRUCTIONS. WE ADVISED ENGS WERE NOT STARTED AND COULD TAXI IN 1-2 MINS. HE SAID TAXI TO AND HOLD SHORT OF D5 AND MONITOR GND ON 121.75. I DID NOT UNDERSTAND THE D5, AS NORMAL PROC IS TO GO TO END OF GA RAMP AND HOLD SHORT OF D7. HOWEVER, HE WAS TOO BUSY TO BREAK IN AND VERIFY, SO WE STARTED ENGS AND WENT TO END OF GA RAMP AND HELD, MONITORING THE GND FREQ. HIS HURRIED INSTRUCTIONS AND INABILITY FOR US TO GET IN A WORD WITH ALL THE FREQ TFC PUT ME IN A RUSHED STATE OF MIND. ALSO, I DIDN'T UNDERSTAND WHY NOT USING GND METERING. GND CTLR CONTACTED US AND CHASTISED US BY SAYING 'I'VE BEEN TRYING TO GET A HOLD OF YOU....' WE HAD JUST STARTED ENGS AND WERE ON THE GND FREQ IMMEDIATELY AFTER ENG START (2 MINS MAX SINCE TALKING TO CLRNC DELIVERY). GND CTLR THEN CLRED 'TO TAXI TO RWY 22L BEHIND THE JET OFF TO YOUR R.' I LOOKED TO THE R AND FOR SOME REASON I TAXIED TO THE R, THIS WAS MY MISTAKE. I KNEW RWY 22L WAS PRETTY MUCH STRAIGHT AHEAD OF MY CURRENT POS AT D7 ON GA RAMP. I DON'T KNOW WHY I TAXIED TO THE R. HOWEVER, WHEN ON TXWY D (WBOUND) AND LOOKING FORWARD, I SAW OTHER ACFT COMING EBOUND BY D5 AND HOLDING FOR ME (THEY KNEW I WAS WRONG DIRECTION). CORRECTIVE ACTION WAS ME CONTACTING GND AND ASKING IF HE WANTED ME TO 'DUCK INTO D5.' AT THIS POINT, I STILL MUST HAVE BEEN THINKING HE WAS SENDING ME TO RWY 22R. THE GND CTLR SAID 'NEGATIVE, DO A 180 DEG TURN AND TAXI TO RWY 22L.' AT THIS POINT, I REALIZED MY MISTAKE, DID THE 180 DEG TURN AND TAXIED TO RWY 22L (AHEAD OF THE ACFT I WAS SUPPOSED TO FOLLOW). NO INCIDENT, NO CLOSE CALL. I TAXIED ABOUT 100 FT IN WRONG DIRECTION BEFORE CORRECTING. NO RWY INCURSION, NO OTHER ACFT INVOLVED. CONTRIBUTING TO THIS, I FEEL, WERE 2 CTLRS TOO BUSY TO 'DEAL' WITH A LITTLE GUY, AND MY PERCEPTION THAT AT ORD THE GA GUYS ARE TREATED DIFFERENTLY, EVEN THOUGH IN MY FEW EXPERIENCES THERE THIS IS NOT THE CASE.
