Assorted fields in Austin and Waco... I haven't seen any really high-grade locations, you know, the ones with in-door fields and what-not.
I actually liked this location a lot. The place was wide and open, leaving lots of room for Scout/Sniper types to roam around and flank their opponents. There was plenty of cover to hide behind, and it was easy enough to move fire-teams around without being seen.
The refs seemed to know what they were about, and one of the refs even played with us a few matches. He had a lot of skill and quality equipment.
The pro shop sells some interesting hardware, and the people running it can fix basic problems easily.
A good field... I'm probably going out there today.
