Narrative:

Fire tanker was departing runway 8 with no radio call on the CTAF. We started to depart runway 26 after making our radio call to do so. We saw each other and both of us aborted the takeoff. Another tanker had just taken off runway 26 and another cessna was doing touch and goes on runway 26. The AWOS said the wind was 200 degrees at 6 KTS, windsock showed wind to be variable, runway indicator pointed down runway 26.
