Sorry to the Frisbee player that I berated at Zilker Park

This morning I was at Zilker Park shooting some video for a job. A group old guys came up and started setting up cones around me. Then one old guy came jogging backwards right past me and asked me if I could move 5 yards. I said "No, I'm shooting a video". But I when I was done with that shot I moved over a bit. They kept looking over at me doing stuff like missing catches near me, running in my path, etc. I ignored them. Finally another guy ran up on me and asked me if I could out of thier outfield because they were gonna be running in that space. I lost it and said that I was working and that I was there first, and that I needed to be in that spot. I said if they didn't like it, they could move over. It's a huge park. The guy kept talking and I cussed him out. For that I am very sorry. I was on a time frame trying to get my work done and got stressed. It doesn't excuse my reaction. Again I'm sorry.
