That would almost for certain be dove season and it looks like a good day! The old limit was 10 and now it's 15. I've been on some fields on opening day when you would limit out in ~15 minutes. It's a cultural and social event, not just hunting.
As for that Texas Ranger, that is a real deal Ranger. I recall seeing Rangers early in my career and they looked just like that. The stories around them were nearly unbelievable today, but when you realize that they started as a paramilitary Indian fighting (actually Indian killing) organization things get a bit clearer. I won't share my two favorite Ranger stories here, but next time some of us raise a cold one, I will.
