Short answer: you guys are right - looks like there are no firework shows in the area.
From what I've read, most of the surrounding towns don't do fireworks because everyone used to go to the Monterrey show. I found a forum that claims there is a show in Santa Cruz that you can see from Cannery Row. However, I couldn't find any info on the city of Santa Cruz's website confirming they had a show. San Jose canceled their show, Salinas doesn't have one, Monterrey canceled their show, etc, etc.
I guess the real fun is happening that night at Cannery Row anyways.
The fireworks will come as legions of squids on parked Japanese I4's blow up their motors after repeatedly bouncing them off the rev limiter to impress people on Cannery Row.
