Ever wonder what happens behind the walls in secure areas of DFW Airport? Come on a private tour of their Administration Building to watch an interactive display of hundreds of flights all over the world, learn about various wildlife and security problems, and then visit the Fire and Police Stations. Our last stop will be Founders’ Plaza, which offers magnificent views of aircraft as they take off and land and provides a radio broadcast of air-traffic-control communications from the FAA tower. We will depart at 9 a.m. a.m. for the 10 a.m. tour, which lasts 2 hours. Be sure to wear comfortable shoes because there will be considerable walking. We will eat at Cheddars at our own expense after the tour and will arrive back about 3 p.m. Cost is $12 per member and $14 per nonmember. The tour is limited by DFW to 30 people, so register soon.
