My neatest observation of one, and most recent, was at Guadalupe River State Park, actually... near the stock tank and picnic tables on Loop 3 of the multi-use trail, just a (very) short walk from campsite #34. Unfortunately, I didn't have my 300mm lens on the camera, and by the time I got it out of the camera bag the two caracaras on neighboring trees had taken flight.

We've also seen them at Brazos Bend State Park near Houston, though it seems to be highly seasonally depenedent on how many raptors you'll see there... at least in our limited experience.
