gunshots by Camino Real Park?

i am near to Camino Real Park and heard a repeated blasting noise. about 8 pops in 5 seconds (estimating). i saw no lights like fireworks but im not sure. this happened around 7pm and im not sure if it actually was or not. if it was firecracker.. who is stupid enough to light them right now while we are in a red flag warning for fire danger?
