SPI ENCOUNTERED NMAC WITH ANOTHER ACFT IN THE TFC PATTERN OF A NON CTLED ARPT.

Narrative

I WAS PRACTICING FOR MY PRIVATE PLT FLT CHK. I WAS DOING TOUCH-AND-GOES AT A LCL UNCTLED FIELD. I CALLED FOR A TA. THE WINDS WERE CALM. THE OTHER TFC IN THE PATTERN WAS USING RWY 7 (7-25). I HAD DONE 4 TOUCH-AND-GOES. THE OTHER TFC DEPARTED THE PATTERN. I WAS ON DOWNWIND FOR ANOTHER TOUCH-AND-GO. AS I STARTED MY TURN TO BASE; I NOTICED ANOTHER AIRPLANE FLYING AT APPROX 1700 MSL (400 FT AGL) THROUGH THE APCH END FOR RWY 7. PATTERN ALT IS 2000 FT; FIELD ELEVATION IS 1200 FT. I MAINTAINED ALT AND TURNED TO THE R; AWAY FROM THE OTHER ACFT. THE ACFT CONTINUED AT THE SAME ALT; FLYING AT A 60 DEG ANGLE OVER THE APCH END OF THE RWY. I CONTINUED MY APCH. AS I TOUCHED DOWN ON THE RWY; THE OTHER ACFT; NOW S AND PARALLEL TO THE FIELD; RADIOED THAT I WAS USING THE WRONG RWY! UP TO THIS POINT; THIS ACFT HAD MADE NO RADIO CALLS REGARDING POS; INTENTIONS; OR TO ASK FOR AN ADVISORY. WHEN HE MADE HIS CALL TO ME; I WAS NEXT TO THE WINDSOCK; WHICH WAS LIMP. HOWEVER; THE SOCK WAS FAVORING RWY 7 (STRAIGHT DOWN THE RWY) ON THE PREVIOUS TOUCH AND GO; AS I THROTTLED UP AND TOOK OFF; THE OTHER AIRPLANE WAS XING THE DEP END OF THE RWY. ONCE AGAIN; I HAD TO TAKE EVASIVE ACTION TO AVOID THE ACFT. AS I TURNED XWIND; THE OTHER ACFT; NOW N OF THE FIELD; RADIOED THAT HE WAS HDG BACK TO AGC (HOME BASE FOR MYSELF AND THE OTHER ACFT). HE DID NOT LAND AT G08. TO SUMMARIZE THE INCIDENT; I WAS USING PROPER UNCTLED FIELD PROCS MAKING ALL RADIO CALLS; ETC. THE OTHER ACFT WAS FLYING AROUND THE UNCTLED FIELD; IN AND OUT OF THE PATTERN; AT A DANGEROUS ALT WITHOUT MAKING ANY RADIO CALLS; EXCEPT TO CHASTISE ME! APPARENTLY; HE THOUGHT THAT IT WAS MORE IMPORTANT TO OBSERVE AND CRITIQUE MY FLYING; THAN IT WAS TO FOLLOW PROPER AND SAFE UNCTLED ARPT TECHNIQUE.
