I was curious if anyone knew what the San Diego county big day record was, or if anyone has seriously tried one? I couldn't find any info while searching online and haven't really heard of anyone doing one. I don't plan on doing a serious big day but I've often wondered what a well-planned, serious effort could get in the county. Surely over 150 species? I feel like with a lot of luck and good planning, 175 species could be within reason.
