The horn was for the annual Tengu Derby. I think this is the 57th annual, mooching only derby. It runs on consecutive Sunday's from daybreak to 11 am. I went out Sunday for the first time and got skunked (along with most participants). Out of 60 participants, there were two fish caught, 6 and 9 lbs. I hope to be out Sunday for my second try (and the last day of this derby).
