Johnny, Thanks for the fun video. I recently took my 14 year old granddaughter, who was visiting from Ft. Worth, to the nearby Old Tunnel State Park bat cave. Next time we'll have to do the one in Bracken. 73, Jerry w5mig
Thanks! That is definitely on my list. SanAntonio is "only" 12 hours away. I'm there for sure. 73 Ron K7RJ
Great video..de K5SL in Haughton,La...I need to make a trip to Bracken. I have 3 bat houses up in backyard, and have over 1200 bats in them. I built a handheld ultrasonic detector and mounted a 9v powered audio amp under it...Your sounds are lil different. I have "clicks" . You can see some of mine with audio on you tube..Look up "bats exiting at 3pm", or another called "crowded bat houses" by Emersombiguns...That is the best video of Bracken I have seen yet...Gl Randy K5SL
