Busy? The AFD says KELA is "attended Mon-Sat irregularly". Here's another thing to watch for at KELA: Skydive Houston is listed as a service there in ForeFlight. Those guys under parachute don't have radios either. The sectional also shows glider ops just east of KELA. They often don't have radios, and they won't go around if they are on final and you pull onto the runway.
