Continued walking around the big field looking for more dragonflies. And I did! I spotted a pair of big dragonflies flying around together. I realized that they were Slender Skimmers, and they were mating! I followed them till they came to stop to rest.
Didn't do that well in my first shot. However, I kept trying until i got another shot that seemed okay.
Soon I lost sight of the mating pair but still had some lonely individuals around.
