There is a private airpark community in the DFW area called Eagle's Nest similar to Pecan Plantation where I live. I flew over there today to return Bob Kibby's generously loaned RV12 throttle cable. After landing I was chased down by a resident on his scooter who demanded to know who briefed me on the landing procedures at Eagles' Nest. Oops...my mistake. I had planned to surprise Bob so I didn't call first. While it turns out the landing procedures are fairly standard they do have a unique requirement. You must turn on the landing lights (during the day) before landing. I was told someone could have been standing on the runway when I landed with no warning to get out of the way.???? I will return to see Bob of course and will abide by the rules. Just thought I would pass on before anyone else makes the mistake I did. Call first!
