I tried to go to any launch I could when I lived in Florida. The bigger the rocket the better, in general. However right before sunrise or right after sunset you get incredible jellyfish in the sky as the rocket leaves the atmosphere. My favorite launch was probably Arabsat, when the two boosters did their boost back burn, the flow of the exhausts between them and the second stage was amazing.

As far as delays, I don’t assume it’ll launch until it launches. Have literally had abort’s at T-1 second. I’ve gone to the same launch four times in a week. It happens. Aborts not RUDs is the rule.
