Narrative:

I came into ftg's airspace and entered the pattern on a 45 degree left downwind and announced all position. We were following a cessna turning left base to final when another plane entered the pattern on a left base. Since that plane went in front of us, we had to extend our downwind. After turning base following the traffic, I turned final. I announced all my position while in the pattern. When I was on about a 1 mi final, the high wing cessna that was following us turned base to final. I didn't see him until he was turning final right where we were on final. It was obvious he didn't see us even after I announced once again that I was short final. In order to avoid that aircraft, I banked right to get out of the way of that aircraft and I left the area to come back and reenter the pattern. Since I had to bank hard right, I ended up going a bit north of the airport. I was aware of den's airspace just to the north of ftg and made every effort to avoid the class B but might have clipped the edge.

Narrative: I CAME INTO FTG'S AIRSPACE AND ENTERED THE PATTERN ON A 45 DEG L DOWNWIND AND ANNOUNCED ALL POS. WE WERE FOLLOWING A CESSNA TURNING L BASE TO FINAL WHEN ANOTHER PLANE ENTERED THE PATTERN ON A L BASE. SINCE THAT PLANE WENT IN FRONT OF US, WE HAD TO EXTEND OUR DOWNWIND. AFTER TURNING BASE FOLLOWING THE TFC, I TURNED FINAL. I ANNOUNCED ALL MY POS WHILE IN THE PATTERN. WHEN I WAS ON ABOUT A 1 MI FINAL, THE HIGH WING CESSNA THAT WAS FOLLOWING US TURNED BASE TO FINAL. I DIDN'T SEE HIM UNTIL HE WAS TURNING FINAL RIGHT WHERE WE WERE ON FINAL. IT WAS OBVIOUS HE DIDN'T SEE US EVEN AFTER I ANNOUNCED ONCE AGAIN THAT I WAS SHORT FINAL. IN ORDER TO AVOID THAT ACFT, I BANKED R TO GET OUT OF THE WAY OF THAT ACFT AND I LEFT THE AREA TO COME BACK AND REENTER THE PATTERN. SINCE I HAD TO BANK HARD R, I ENDED UP GOING A BIT N OF THE ARPT. I WAS AWARE OF DEN'S AIRSPACE JUST TO THE N OF FTG AND MADE EVERY EFFORT TO AVOID THE CLASS B BUT MIGHT HAVE CLIPPED THE EDGE.
